AP7366-12W5-7

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

AP7366-12W5-7 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 (2.2V to 6V operating range); bypass to ground through at least a 1µF MLCC capacitor.
2 GND power_in Ground.
3 EN input Active-high enable input; logic-high at or above 1.0V turns the device on, logic-low at or below 0.3V turns it off, and it can be tied to IN if unused.
4 NC unconnected No connection on the fixed-output SOT25 version.
5 OUT power_out Voltage output pin (1.2V fixed for this part); bypass to ground through a 1µF MLCC capacitor.

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 reduce noise. For PCB layout, a wide copper trace is required for both IN and GND pins. A lower ESR capacitor type allows the use of less 8
