PJ75CL33SC

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

PJ75CL33SC 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.
2 VOUT power_out Regulated output voltage (3.0V to 12V fixed options), which requires a minimum 1uF capacitor from VOUT to ground for stability.
3 VIN power_in Power input with a 3V to 40V supply range, which must stay above VOUT by the dropout voltage for the device to regulate.
