PJ73HM50SC

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

PJ73HM50SC 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 for the regulator; the datasheet lists it only as 'Ground' with no electrical limits.
2 VOUT power_out Regulated output of the 5.0V (PJ73HM50SC) version, rated for 500mA within the package power dissipation limit, with an absolute maximum of -0.3V to 6V on this pin.
3 VIN power_in Power input with a 3V to 20V supply range and an absolute maximum of -0.3V to 25V.
