MC78M08BDTRKG

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

MC78M08BDTRKG from onsemi, in a 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 VI power_in Unregulated positive input voltage. Absolute maximum 35 Vdc (40 Vdc for 20 V/24 V options). For 8 V output operation, VI ≥ ~10.5 V is recommended (dropout ≈ 2.0 V typ).
2 GND power_in Common/ground reference. Also serves as the thermal path: the DPAK heatsink surface (terminal 4 in the case outline drawing) is internally connected to Pin 2.
3 VO power_out Regulated +8.0 V output (7.70-8.30 V for MC78M08B/C, 7.84-8.16 V for MC78M08AB/AC over temperature). Rated for 500 mA continuous with adequate heatsinking; internal short-circuit current limit ≈ 350 mA typ.
4 TAB passive Exposed thermal pad / heatsink surface on the back of the DPAK-3 package. Internally connected to Pin 2 (GND). Solder to a copper pour for heat dissipation.
