AP7366-W5-7

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

AP7366-W5-7 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, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Voltage input pin, which should be bypassed to ground with at least a 1µF MLCC capacitor; the input range is 2.2V to 6V.
2 GND power_in Ground pin; the datasheet states no further electrical limits for this pin.
3 EN input Active-high enable input that turns the regulator on when driven above VIH (minimum 1.0V) and off below VIL (maximum 0.3V); it can be tied to IN for always-on operation.
4 ADJ input Output feedback pin that sets the output voltage from 0.8V to 5.0V through an external resistor divider referenced to the 0.8V internal reference, with R2 kept below 80kΩ.
5 OUT power_out Voltage output pin, which should be bypassed to ground with a 1µF MLCC capacitor and supplies up to 600mA.

CAD (KiCad official)

  • Symbol: AP7366-W5-7
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-25, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.1 mm tall, datasheet A, nominal). Neither the vendor nor KiCad ships a 3D model for this package, so 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: ap7366-w5-7-etched.step / ap7366-w5-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7366-w5-7.step / ap7366-w5-7.glb are the bare package body.
