MC79M05CDTRKG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DPAK-3

MC79M05CDTRKG from onsemi, in a DPAK-3. 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 pin; a common ground is required between the input and the output voltages.
2 VI power_in Negative unregulated input; the maximum input voltage is −35 Vdc, and the input must remain typically 1.1 V more negative than the output even at the high point of the input ripple.
3 VO power_out Regulated negative output of −5.0 V nominal for the MC79M05, capable of delivering output currents in excess of 0.5 A with adequate heatsinking.
