AP7315-28SA-7

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

AP7315-28SA-7 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 VIN power_in Power input pin; the datasheet gives a wide input range of 1.7V to 5.25V (absolute maximum 6.0V).
2 VOUT power_out Power output pin; the regulator delivers up to 150mA guaranteed output current, with fixed output voltage (1.1V to 3.3V family).
3 GND power_in Ground pin; connect to the external circuit ground through a low-impedance trace, with the input and output capacitors placed close to the pins.

Materials and finish

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

Part Material Colour / plating Datasheet says Page
contacts copper capacitor is recommended between VIN and GND pins to decouple input power supply glitch. This input capacitor must be located as close as possible to the device to assure input stability and reduce no 11

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

  • Symbol: AP7315-28SA-7
  • 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: ap7315-28sa-7-etched.step / ap7315-28sa-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7315-28sa-7.step / ap7315-28sa-7.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (24 pp, sha256 3ce3186b60b69e99, 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).
