AP7331-WG-7

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

AP7331-WG-7 from Diodes Incorporated, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Voltage input pin. Operating range 2V to 6V (abs max 7V). Bypass to GND with at least a 1uF capacitor close to the pin.
2 GND power_in Ground return for the regulator.
3 EN input Enable input, active high. Device turns on when EN is at logic high (VIH >= 1.4V); shutdown when low (VIL <= 0.4V). Abs max VIN + 0.3V. EN input current +/- 1uA max.
4 NC unconnected No connection. Leave floating or tie to a static net.
5 OUT power_out Regulated voltage output pin, up to 300mA. Bypass to GND with a 1uF ceramic capacitor (low ESR) for stability.
