AP7381-70Y-13

Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-89

AP7381-70Y-13 from Diodes Incorporated, in a SOT-89. 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 VOUT power_out Regulated output voltage; the absolute maximum output voltage is -0.3 V to 8 V and the output current is rated at 150 mA.
2 GND power_in Ground pin for the regulator, which the datasheet does not give a separate electrical limit for.
3 VIN power_in Input voltage with a recommended supply range of 3.3 V to 40 V and an absolute maximum rating of -0.3 V to 45 V.
