AP7381-50Y-13

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

AP7381-50Y-13 from Diodes Incorporated, in a SOT-89. 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 VOUT power_out Regulated output voltage. Fixed 5.0V nominal on the -50 option, ±2% accuracy. Requires a >=2.2µF low-ESR ceramic capacitor to GND for stability; supplies up to 150mA (current-limited).
2 GND power_in Device ground and return for the internal reference/error amplifier. Ground current is typically 2.5µA at no load and ~25µA at 100mA load.
3 VIN power_in Unregulated supply input. Recommended operating range 3.3V to 40V (absolute max 45V). Bypass with a >=1µF ceramic capacitor close to the pin.
