PJ78L06SQ

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

PJ78L06SQ from PJSEMI, in a SOT-89. 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 OUT power_out Regulated 6 V output that delivers up to 100 mA, with internal thermal overload protection and short-circuit limiting.
2 GND power_in Common ground reference pin; the datasheet gives no electrical limit specific to this pin.
3 IN power_in Unregulated input pin with a maximum input voltage of 30 V, used with a 0.33 µF input capacitor (C1) in the application circuit.
