AP7331-15WG-7

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

AP7331-15WG-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, 2V to 6V. Bypass to ground through at least a 1µF ceramic capacitor placed close to the device.
2 GND power_in Ground reference for the regulator.
3 EN input Enable input, active high. VIH ≥ 1.4V turns the regulator on; VIL ≤ 0.4V shuts it down. Tie to IN for always-on operation. Absolute max VIN + 0.3V.
4 NC unconnected No connection. Present only on the fixed-output SOT25 variant (the ADJ variant uses this pin for the ADJ feedback input).
5 OUT power_out Regulated voltage output pin (1.5V fixed for -15 suffix, up to 300mA). Bypass to ground through a 1µF ceramic capacitor (ESR 10mΩ-200mΩ, X7R/X5R) placed close to the device.
