PJ56L50SE

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

PJ56L50SE from PJSEMI, in a SOT-23-5. 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 VIN power_in Power input voltage; the datasheet gives a recommended supply range of 5 to 60 V, with an absolute maximum VIN-to-GND voltage of -0.3 to +80 V.
2 GND power_in Ground reference for the regulator; decoupling capacitors should be placed close to the VIN and GND pins with wide copper traces.
3 NC unconnected No connection; the pin is not connected internally.
4 NC unconnected No connection; the pin is not connected internally.
5 VOUT power_out Regulated output voltage; the output can deliver up to 150 mA, with an absolute maximum VOUT-to-GND voltage of +6 V, and requires a minimum 10 µF ceramic output capacitor placed close to VOUT and GND.
