KIA7912PI-U

KEC Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220F

KIA7912PI-U from KEC Semicon, in a TO-220F. 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 -12V regulator.
2 INPUT power_in Negative input voltage pin; absolute maximum VIN is -35 V, with VIN = -18 V used for the electrical characteristics.
3 OUTPUT power_out Regulated -12 V output (-12.5 V min to -11.5 V max at Tj=25C), providing output current in excess of 1.0 A with internal short-circuit limiting (typ. 1.9 A).
