CJ78L12-TA

Changjiang Electronics Tech (CJ) · Linear Voltage Regulators (LDO) · TO-92-2.54mm

CJ78L12-TA from Changjiang Electronics Tech (CJ), in a TO-92-2.54mm. 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 12V output (Vo 11.5V min to 12.5V max at 25°C), maximum output current 0.1A, with a 0.1µF bypass capacitor recommended close to the regulator.
2 GND power_in Ground reference pin, common to the input and output bypass capacitors.
3 IN power_in Unregulated input voltage, absolute maximum 35V, with a 0.33µF bypass capacitor recommended close to the regulator.
