AP2120N-1.5TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

AP2120N-1.5TRG1 from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 GND power_in Ground reference pin for the regulator.
2 VOUT power_out Regulated output voltage, which needs more than 1µF of output capacitance with ESR from 0.01Ω to 100Ω for stability, and ceramic capacitors are recommended.
3 VIN power_in Input voltage with a recommended range of 2V to 6V (absolute maximum 6.5V), and a 1µF input filter capacitor is required.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: AP2120N-1.5TRG1
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.0 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: ap2120n-1-5trg1-etched.step / ap2120n-1-5trg1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap2120n-1-5trg1.step / ap2120n-1-5trg1.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Diodes Incorporated datasheet (19 pp, sha256 66be4c8fbb47afd5, retrieved 2026-11-13, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
