AP139-30WG-7

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

AP139-30WG-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 VIN power_in Power supply input accepting 2.7V to 5.5V (absolute maximum +6V).
2 GND power_in Ground pin; a quiet ground termination is desirable.
3 EN input Enable pin: output ON at 1.7V or above, OFF at 0.8V or below, with enable pin current below 0.1µA.
4 BYP passive Bypass signal pin; a 10nF capacitor between BYP and ground is used for low-noise applications.
5 VOUT power_out Regulated output delivering up to 300mA, stable with a low-ESR output capacitor of 1.0µF or greater.
