PJ54M30SC

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

PJ54M30SC 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 gives no separate limit for this pin, and the input and output capacitors are to be placed close to the device with GND as the return.
2 VOUT power_out Regulated output for the fixed-voltage options (1.8V, 2.8V, 3V, 3.3V, 5V, 6V) delivering up to 350mA, with absolute maximum VOUT to GND of -0.3 to +6V.
3 VIN power_in Power input with a recommended supply range of 3 to 45V and an absolute maximum VIN to GND of -0.3 to +55V.
