LR78M05D

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

LR78M05D from LRC, in a TO-252-2(DPAK). 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; absolute maximum input is 35 V for VO = 5 V to 18 V (40 V for VO = 24 V).
2 GND power_in Common ground reference pin of the three-terminal regulator.
3 Output power_out Regulated 5 V output of the LR78M05D, rated for output current up to 0.5 A.
