AP7361-33E-13

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

AP7361-33E-13 from Diodes Incorporated, in a SOT-223. 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 The input of the regulator, specified for 2.2V to 6.0V operation with a 6.5V absolute maximum; bypass to ground with at least 1µF ceramic capacitor.
2 GND power_in Ground reference pin for the regulator.
3 OUT power_out The regulator output; bypass to ground with at least 2.2µF ceramic capacitor (10mΩ to 300mΩ ESR), with a larger capacitor recommended for improved AC load response.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).
