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

PJ78L05SA from PJSEMI, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated positive output voltage (nominal +5.0 V, 4.8-5.2 V at TJ=25°C). Supplies up to 100 mA. Requires a 0.1 µF output capacitor (CO) to GND for stability.
2 VIN power_in Unregulated positive input supply. Absolute maximum 30 V (for VOUT=5-10 V variants). Requires a 0.33 µF input capacitor (CI) to GND. Dropout voltage typically 1.7 V.
3 GND power_in Common ground reference for both input and output. Carries the quiescent current (typ 2.0 mA, max 5.5 mA).
