PCA9685PW,118

AL58263A is a Diodes Incorporated 16-channel constant-current LED driver with 16-bit grayscale Adaptive Pulse Density Modulation (APDM) — for indoor/outdoor LED video displays, variable message signs, traffic signs, billboards and LCD backlighting where uniform brightness and flicker-free dimming decide display quality. The APDM architecture is the selection point: by mitigating non-ideal output-current distortion from non-symmetric transient responses and separating frame waveform components, it improves output-current linearity and raises the system refresh rate versus conventional PWM dimming. It runs from 3.0 V to 5.0 V, supports output channel voltages up to 15 V, interfaces with a 25 MHz data clock, and delivers up to 45 mA of precise programmable current per channel. Each channel current is set through the digital interface, while the overall range is set by one external sensing resistor plus two independent 4-bit global current-gain controls (separate Group A and Group B banks). Accuracy is 1.5% typical / 3.5% maximum channel-to-channel current skew and 3% typical / 6% maximum chip-to-chip skew, with 0.1%/V output-voltage regulation, and built-in LED open/short diagnostics whose results are stored in registers for MCU readout, plus a 155°C thermal alarm with 15°C hysteresis. It comes in a thermally enhanced TSSOP-24EP package with exposed pad, rated -40°C to +105°C ambient. Selection advice: do not treat the A variant as a drop-in identical to the base AL58263 — the base part runs 3.0 V to 5.5 V with up to 55 mA per channel and a single 6-bit global current control, so re-check voltage headroom, current budget and gain-register programming when swapping. Solder the exposed thermal pad and provide a generous copper spread for full-current operation. Featured on Mouser New Products (2026-10-15).

AP3031KTR-G1 is a Diodes Incorporated inductor-based DC/DC boost converter for white LED backlight arrays — for 7 to 10 inch LCD panel lighting: 2.7V to 16V input, 1MHz fixed switching frequency, 1.4A switch current limit, 200mV feedback voltage, up to 92% efficiency, output overvoltage protection, undervoltage lockout, built-in soft start, thermal shutdown, SOT-23-6 package. The 1MHz constant-frequency control means a 1mm-tall 4.7µH inductor and 0.47µF output capacitor are sufficient, so backlight circuits stay compact; the built-in standby mode supports high-frequency PWM dimming. Business impact: LED backlight drivers are high-volume commodity parts where supply continuity matters — a mature part with multi-channel availability protects production schedules. Selection advice: the KTR code is the SOT-26 package in tape and reel — for SOIC-8 consider the alternate package option; verify the LED string voltage stays within the overvoltage protection threshold per the Diodes datasheet.

TLC6C5712QPWPRQ1 is a Texas Instruments automotive 12-channel constant-current sink LED driver, 75 mA per channel, 12-bit dot correction, 3 to 5.5 V supply, AEC-Q100 qualified, in HTSSOP-28 — the cluster and backlight driver for automotive displays and interior lighting. The per-channel 12-bit dot correction with LED open, adjacent-pin short and short-to-ground diagnostics is the selection point: uniform brightness across the panel plus fault reporting the body controller can act on. Selection advice: outputs are constant-current sinks rated to 7 V — verify your LED string forward voltage stays within the sink headroom at the programmed current, and use the exposed PowerPAD soldered to the PCB since 12 channels at 75 mA dissipate real power. The PWP suffix is the HTSSOP-28 package, R = tape and reel (2000). For higher-current or more channels compare the TLC6C59xx family. Parameters verified against the TI TLC6C5712-Q1 datasheet and Mouser listings.

A4988SETTR-T is an Allegro MicroSystems DMOS microstepping stepper motor driver in QFN-28, tape and reel — for 3D printers, CNC machines and consumer motion control where a proven low-cost stepper driver matters. Built-in translator with full-step down to 1/16 microstepping, 35 V and ±2 A drive is the selection point: one STEP pulse equals one microstep, no phase tables to program. Selection advice: the SETTR-T suffix denotes the QFN-28 package in tape and reel; the SET temperature grade covers −20 °C to +85 °C. Against the TI DRV8825 on this site (45 V, 2.5 A, 1/32 step): the A4988 costs less and is the 3D-printing classic, but tops out at 1/16 microstepping and lower voltage — pick it when the motor fits within 35 V and 2 A. Synchronous rectification keeps dissipation low; thermal shutdown and short-circuit protections are built in. On 3D-printer StepStick-style modules the A4988 and DRV8825 footprints are largely interchangeable — but check driver orientation, microstepping jumpers and current setting before swapping, as the two parts differ. Parameters verified against distributor and manufacturer documentation.

ADP151AUJZ-3.3-R7 is an Analog Devices ultralow-noise 3.3 V LDO regulator in TSOT-23-5, tape and reel — for noise-sensitive rails: RF, VCO and PLL supplies where output noise matters more than current. 9 microvolt RMS noise with no bypass capacitor required is the selection point: ultralow noise without the extra capacitor that competing LDOs need. Selection advice: the R7 suffix denotes tape and reel on a 7-inch reel; against the LD1086DT33TR on this site — the ADP151 is the 200 mA precision part, the LD1086 the 1.5 A workhorse. 2.2 V to 5.5 V input, 150 mV dropout at 200 mA, 70 dB PSRR at 10 kHz. −40 °C to +125 °C. ADI lists this part as Active through distribution. Parameters verified against distributor and manufacturer documentation.

AMS1117-3.3 is a 3.3 V, 1 A low-dropout linear regulator in a SOT-223 package, for general-purpose power rails in embedded and consumer designs. Its advantage is simplicity: a fixed 3.3 V output with minimal external components, which keeps power-tree cost and design effort low where efficiency is not the binding constraint. Selection advice: the -3.3 suffix fixes the output voltage — the AMS1117 family also ships in adjustable and other fixed-voltage versions that are not interchangeable, so match the full code. As a linear regulator it dissipates excess voltage as heat, so verify your input-to-output differential and load current against thermal limits, and consider a switching regulator where efficiency matters. This is another heavily counterfeited commodity part: require lot and date-code traceability.

AP2112K-1.2TR-G1 is a Diodes Incorporated AP2112 fixed 1.2 V low-dropout regulator — 600 mA output, CMOS design with enable pin, 55 µA quiescent current, in SOT-25, tape-and-reel packing (TR), -40 to +85 °C. The 1.2 V fixed output is the selection point: a ready-made core-voltage rail for MCUs, FPGAs and RF modules from a 2.5-6 V input, with enable control for power sequencing. Selection advice: the enable pin with discharge resistor simplifies sequencing — tie it high only if you truly never need shutdown. The 600 mA rating suits digital cores and sensors; for higher current choose a larger LDO family. Note the G1 suffix is the green (lead-free) variant and TR is reel packing. Evidence: Diodes AP2112 datasheet and distributor listings confirm 600 mA, 1.2 V fixed, SOT-25 and reel packing. Match the full AP2112K-1.2TR-G1 code for voltage, package and packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AP2112K-1.8TRG1 is a Diodes Incorporated AP2112 fixed 1.8 V CMOS low-dropout linear regulator — 600 mA guaranteed, enable pin with auto-discharge, in SOT-25, tape-and-reel packing, 2.5 to 6 V input, -40 to +85 °C. The 250 mV typical dropout at 600 mA with ±1.5% output accuracy is the selection point: a true 1.8 V core rail from a 3.3 V or 5 V bus in a 5-pin SOT-25. Selection advice: the enable pin plus the 60 Ω auto-discharge is the feature to design around — when disabled the output is actively pulled to ground, giving clean power sequencing instead of a floating rail that back-powers downstream logic. With 55 µA quiescent and 0.01 µA standby current it suits battery-powered 1.8 V MCU, FPGA-core and memory rails; for 2.5 V rails use the AP2112K-2.5TRG1 sibling rather than this 1.8 V code. The TRG1 suffix is tape and reel for SMT production. Evidence: Diodes AP2112 datasheet and Farnell/element14 listings confirm 1.8 V, 600 mA, enable with auto-discharge, SOT-25 and 2.5-6 V input. Match the full AP2112K-1.8TRG1 code for voltage and packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AP2112K-2.5TRG1 is a Diodes Incorporated AP2112 fixed 2.5 V CMOS low-dropout linear regulator — 600 mA guaranteed, enable pin with auto-discharge, in SOT-25, tape-and-reel packing, 2.5 to 6 V input, -40 to +85 °C. The 250 mV typical dropout at 600 mA with ±1.5% output accuracy is the selection point: a 2.5 V rail for ADC references, legacy logic and telecom interfaces from a 3.3 V or 5 V bus. Selection advice: mind the input window — with a 2.5 V output and 2.5 V minimum input rating, the supply must stay clearly above 2.5 V plus dropout under load, so a sagging 3.3 V bus at full 600 mA deserves a dropout calculation before you commit. Like its 1.8 V sibling, the enable pin with 60 Ω auto-discharge gives clean power-down sequencing, and 55 µA quiescent with 0.01 µA standby suits battery-powered designs. Choose this 2.5 V code for 2.5 V rails only — for 1.8 V rails use AP2112K-1.8TRG1; fixed means fixed. The TRG1 suffix is tape and reel for SMT production. Evidence: Diodes AP2112 datasheet and distributor listings confirm 2.5 V, 600 mA, enable with auto-discharge, SOT-25 and 2.5-6 V input. Match the full AP2112K-2.5TRG1 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AP2112K-2.6TR-G1 is a Diodes Incorporated AP2112 fixed 2.6 V low-dropout regulator — 600 mA output, CMOS design with enable pin, 80 µA quiescent current, maximum 0.4 V dropout at 600 mA, in SOT-25, tape-and-reel packing (TR), -40 to +85 °C. The 2.6 V fixed output is the selection point: a less common rail for memory, RF and sensor supplies from a 2.5-6 V input, with enable control for power sequencing. Selection advice: the enable pin with discharge resistor simplifies sequencing — tie it high only if you truly never need shutdown. The 600 mA rating suits digital cores and peripherals; for higher current choose a larger LDO family. Note the G1 suffix is the green (lead-free) variant and TR is reel packing — the M package code is the SOIC-8 alternative. Evidence: Diodes/BCD AP2112 datasheet (ordering table) and distributor listings confirm 600 mA, 2.6 V fixed, SOT-25 and reel packing. Match the full AP2112K-2.6TR-G1 code for voltage, package and packing.
