PJ56L33SC

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

PJ56L33SC 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 pin; the input and output capacitors should be connected between VIN/VOUT and this GND pin, with wide copper traces for VIN and GND.
2 VOUT power_out Regulated output voltage; a minimum 10µF ceramic output capacitor (X7R or X5R) is required for stability and should be placed as close as possible to VOUT and GND.
3 VIN power_in Power input with a 5V to 60V supply range; a 1µF ceramic input capacitor should be placed as close as possible to the device between VIN and GND.
