PJ73AL36SC

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

PJ73AL36SC from PJSEMI, in a SOT-23-3. 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 GND power_in Ground reference pin; input and output capacitor ground connections must use as wide and as short a copper trace as practical.
2 VOUT power_out Regulated output voltage; a minimum 10µF ceramic output capacitor (X7R or X5R) is required, placed as close as possible to VOUT and GND.
3 VIN power_in Power input; rated up to 20V in recommended operation (absolute maximum supply voltage -0.3 to +22V), with a 1µF ceramic input capacitor placed close to the device.
