MANUFACTURER PART RECORD

AP2112K-1.2TR-G1

Diodes Incorporated

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.

SELECTION GUIDANCE

AP2112K-1.2TR-G1 selection guidance

AP2112K-1.2TR-G1 is a AP2112 from Diodes Incorporated, orderable in SOT25. The ordering code fixes the exact electrical and thermal configuration you receive, so match it character-for-character against your BOM at your real operating point before committing.

The table below lines up this series' orderable codes on our catalog — AP2112K-1.8TRG1, AP2112K-2.5TRG1, AP2112K-2.6TR-G1, AP2112K-3.3TRG1 — against AP2112K-1.2TR-G1. Same platform, different suffix-defined configurations; choose by package and packing fit for your line, and never swap codes on the series name alone.

When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

COMMON QUESTIONS

AP2112K-1.2TR-G1 FAQ

What is the difference between AP2112K-1.2TR-G1 and AP2112K-1.8TRG1, AP2112K-2.5TRG1, AP2112K-2.6TR-G1?

Same Diodes Incorporated die family, different orderable SKUs: AP2112K-1.8TRG1: Fixed 1.8 V output; AP2112K-2.5TRG1: Fixed 2.5 V output; AP2112K-2.6TR-G1: Compared with AP2112K-3.3TRG1, this code has a 2.6 V fixed output and SOT25 package. A voltage or package change is not a drop-in replacement without electrical and PCB review.. The trailing characters of the part number are what you actually buy — AP2112K-1.2TR-G1 designates the SOT25 build. Never substitute a near-identical code on assumption; confirm every character against the BOM line.

What operating conditions must AP2112K-1.2TR-G1 be checked against?

For this AP2112 device (SOT25), the checks that matter are input/output voltage and current, thermal design at your load, and the package/packing suffix on the ordering code. Confirm all four against the Diodes Incorporated datasheet for your operating point before purchase.

What is the difference between package and packing for AP2112K-1.2TR-G1?

Package and packing answer different questions for AP2112K-1.2TR-G1: the package (SOT25) is what gets soldered to your board, while packing is how the parts arrive at your line — reel, tube, tray or cut tape. Lots vary, so name the packing format you need in the RFQ and we confirm it against the offered lot.

How do I request a quotation for AP2112K-1.2TR-G1?

Tell us the full AP2112K-1.2TR-G1 order code, the maker (Diodes Incorporated), how many you need, reel or tray preference and acceptable date codes — one message is enough. Expect our quotation back within 24 hours.
