AP7315DQ-25W5-7

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

AP7315DQ-25W5-7 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; operating input range is 1.7V to 5.25V (6.0V absolute maximum).
2 GND power_in Ground pin.
3 EN input Enable pin that must be driven high or low and must not float; high (1.3V to 5.25V) enables the regulator and low (0 to 0.5V) puts it into shutdown.
4 NC unconnected No connection.
5 VOUT power_out Power output pin; fixed 2.5V output for this variant with 150mA guaranteed output current and output discharge when disabled.

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-25W5-7
  • 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-25w5-7-etched.step / ap7315dq-25w5-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7315dq-25w5-7.step / ap7315dq-25w5-7.glb are the bare package body.
