PJ7905TE

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

PJ7905TE from PJSEMI, in a TO-252. 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 of the regulator, common to the input and output.
2 VIN power_in Negative input voltage pin, with input voltage up to -35V (absolute maximum) and a 2.2 µF input capacitor shown in the typical application circuit.
3 VOUT power_out Regulated negative output of -5V for the PJ7905TE, delivering up to 1.5A, with a 1 µF output capacitor shown in the typical application circuit.
