LD1086V-DG

LD1086BV-DG is an STMicroelectronics LD1086 adjustable 1.5 A low-dropout regulator in TO-220 — 1.25 to 28.5 V output set by two resistors, up to 30 V input, typical dropout 1.3 V at 1.5 A, ±1% tolerance at 25 °C, tube packing (DG suffix), -40 to +125 °C. The TO-220 through-hole package is the selection point: the best thermal path of the LD1086 family for high-dissipation rails, with a heatsink mounting hole and pin-to-pin compatibility with older 3-terminal adjustable regulators per ST. Selection advice: this is the adjustable version — confirm the feedback divider in your BOM, and note the automotive grade is the separate Y-suffix code, not this catalog -DG code. Only a 10 µF minimum output capacitor is needed for stability, and overcurrent plus thermal limits are built in. For surface-mount assembly choose the DPAK (BDTTR) or D2PAK variants instead. Evidence: ST LD1086 datasheet order-code table and distributor listings confirm adjustable, 1.5 A, TO-220, tube packing. Match the full LD1086BV-DG code for output type, 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.

LD1086V33-DG is an STMicroelectronics fixed 3.3 V 1.5 A low-dropout regulator in TO-220 — fixed 3.3 V output (±2% full range), 1.5 A guaranteed output, 1.3 V typical dropout at 1.5 A, 79 dB PSRR at 120 Hz, over-current and thermal protection, tube packing (DG), -40 to +125 °C. The fixed 3.3 V output is the selection point: no external divider resistors needed — the TO-220 mounting tab handles full 1.5 A with a bolt-on heatsink for 3.3 V rails. Selection advice: the V33 code is the fixed 3.3 V TO-220 version — the adjustable V-DG code needs an external divider, and D2TTR/DTTR are surface-mount codes, so match the full LD1086V33-DG code for output type, package and packing. DG indicates tube packing, not reel. Evidence: ST LD1086 datasheet (Doc ID 6739) and DigiKey listings confirm fixed 3.3 V, 1.5 A, TO-220 and tube packing, Active status. Match the full LD1086V33-DG code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LD1086BDTTR is an STMicroelectronics LD1086 adjustable 1.5 A low-dropout regulator — 1.25 to 28.5 V output set by two resistors, up to 30 V input, typical dropout 1.3 V at 1.5 A, ±1% tolerance at 25 °C, in DPAK (TO-252), tape-and-reel packing (TR), -40 to +125 °C. The adjustable output in a compact DPAK is the selection point: one part covers any rail from 1.25 V up with the efficiency advantage that quiescent current flows into the load, unlike PNP LDOs. Selection advice: pin-to-pin compatible with older 3-terminal adjustable regulators per ST, so it upgrades LM317-style layouts — but it is NOT a fixed-voltage part, so confirm the feedback divider values in your BOM. Only a 10 µF minimum output capacitor is needed for stability, and overcurrent plus thermal limits are built in. Evidence: ST LD1086 datasheet and DigiKey listings confirm 1.5 A adjustable, 30 V max input, DPAK and reel packing. Match the full LD1086BDTTR code for output type, 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.

LD1086D2M33TR is an STMicroelectronics LD1086 fixed 3.3 V low-dropout regulator — 1.5 A output, up to 30 V input, typical dropout 1.3 V at 1.5 A, ±1% output tolerance at 25 °C, in D2PAK-3, tape-and-reel packing (TR), -40 to +125 °C. Pin-to-pin compatibility with the older 3-terminal adjustable regulators is the selection point: a drop-in upgrade path from classic LM317-style layouts with better dropout and tolerance. Selection advice: the 1.5 A rating needs real copper — size the D2PAK thermal pad and board pours for your actual (Vin − 3.3 V) × Iout dissipation, or the thermal limit will throttle the rail. Only a 10 µF minimum output capacitor is needed for stability, and overcurrent plus thermal protection are built in. Note the automotive grade exists only for adjustable versions in TO-220/DPAK — this fixed 3.3 V D2PAK code is the standard catalog grade. Evidence: ST LD1086 datasheet and distributor listings confirm 1.5 A, 3.3 V fixed, 30 V max input, D2PAK and reel packing. Match the full LD1086D2M33TR 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.

The D2PAK (TO-263) package is the selection point: adjustable. Selection advice: do not substitute another LD1086 package code without checking the footprint. Match the full LD1086D2MTR code for package, output type and packing.

LD1086PUR is an STMicroelectronics adjustable 1.5 A low-dropout regulator in DFN8 (4x4, exposed pad) — 1.25 V to 28.5 V adjustable output with two external resistors, 1.5 A guaranteed output, 1.3 V typical dropout at 1.5 A, ±1% output tolerance at 25 °C, 88 dB PSRR at 120 Hz, tape-and-reel packing (UR), -40 to +125 °C. The DFN8 package is the selection point: the smallest LD1086 footprint for dense boards where the exposed pad dumps heat to the PCB — thermal vias under the pad are required for full 1.5 A. Selection advice: the PUR code is the DFN8 adjustable version — the D2TTR code is D2PAK and V-DG is TO-220, so match the full LD1086PUR code for package. It is pin-to-pin compatible with older 3-terminal adjustable regulators, but verify the resistor divider for your target voltage. Evidence: ST LD1086 datasheet (Doc ID 6739) and distributor listings confirm 1.5 A, adjustable, DFN8 and reel packing. Match the full LD1086PUR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

5 V 1.5 A positive linear voltage regulator with 2% output tolerance, thermal overload and short-circuit protection, in TO-220. Manufacturer status: active. The L7805 is the archetypal 5 V rail: built-in thermal and short-circuit protection makes it nearly indestructible in the field, which is why it remains the default choice for simple, robust 5 V supplies. Selection advice: the CV suffix denotes this package and grade configuration — the L78 family spans many output voltages and packages that are not interchangeable, so match the full L7805CV code to your footprint. At 1.5 A with a large dropout, heatsinking is mandatory — verify your thermal design, or choose a switching regulator where efficiency matters.

ST lists LM317T as ACTIVE — an adjustable three-terminal positive voltage regulator, 1.2 V to 37 V output, TO-220 package. Adjustability is the procurement advantage: one part number covers any rail from 1.2 V to 37 V with two resistors, so it replaces a shelf of fixed-voltage regulators and simplifies spares. Selection advice: the T suffix denotes the TO-220 through-hole package — the LM317 also ships in DPAK, SOT-223 and other SMD packages under different suffixes, so match the full LM317T code to your footprint and heatsinking plan. As a linear regulator, verify input-to-output differential and load current against thermal limits. Parameters verified against the ST official product page.
