AP7315DQ-28W5-7

Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-25

AP7315DQ-28W5-7 from Diodes Incorporated, in a SOT-25. 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 specifies a VIN range of 1.7V to 5.25V with a 6.0V absolute maximum rating.
2 GND power_in Ground pin, which should be connected to the external circuit ground to reduce voltage drop caused by trace impedance.
3 EN input Enable pin that must be driven high or low and must not float; EN input high is 1.3V to 5.25V and input low is 0V to 0.5V, with a 6.0V absolute maximum rating.
4 NC unconnected No connection.
5 VOUT power_out Regulated power output pin; the device guarantees 150mA output current and folds back to approximately 55mA (typical) on a short to ground.

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: AP7315DQ-28W5-7
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-25, generated on the KiCad land (body 1.6 x 2.8 mm, terminals on the pads, 1.1 mm tall, datasheet A, nominal). 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: ap7315dq-28w5-7-etched.step / ap7315dq-28w5-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7315dq-28w5-7.step / ap7315dq-28w5-7.glb are the bare package body.

  • Datasheet: Diodes Incorporated datasheet (13 pp, sha256 cb08ea5a5f4d86b9, 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).
