MC78M05ACDTRKG

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

MC78M05ACDTRKG 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 Input power_in Unregulated input voltage to the regulator; the absolute maximum input is 35 Vdc for the 5.0 V-18 V option, and a 0.33 µF or larger low-ESR bypass capacitor is recommended directly across the input when the supply filter is remote.
2 Ground power_in Common ground reference for the regulator; the heatsink surface (tab) is connected to this pin.
3 Output power_out Regulated 5.0 V output, rated for up to 500 mA with adequate heatsinking.
