AP7361C-25ER-13

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223R

AP7361C-25ER-13 from Diodes Incorporated, in a SOT-223R. 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 GND power_in Ground reference pin for the regulator.
2 OUT power_out The regulator output; bypass to ground with at least a 2.2µF ceramic capacitor, and a larger capacitor is recommended for improved AC load response.
3 IN power_in The regulator input; bypass to ground with at least a 1µF ceramic capacitor.
