MC79M12CDTRKG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

MC79M12CDTRKG from onsemi, in a TO-252-2(DPAK). 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 GND power_in Ground reference. A common ground is required between the input and output voltages.
2 VI power_in Negative supply input. Absolute maximum VI = −35 Vdc. For MC79M12, VI must be typically 1.1 V more negative than VO even at input ripple peak (dropout).
3 VO power_out Regulated −12 V output (nominal, ±4% tolerance). Delivers up to 500 mA with adequate heatsinking. Recommended 1.0 µF output capacitor for stability and transient response.
4 TAB power_in Metal tab, electrically connected to GND (pin 1). Used for heatsinking and PCB thermal dissipation. On DPAK, this is the drain/back-side pad.
