L78M05ABV-DG

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

L78M05ABV-DG from STMicroelectronics, in a TO-220. 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 DC input voltage, absolute maximum 35 V for VO = 5 to 18 V, bypassed with CI of 0.33 µF or larger close to the pin.
2 GROUND power_in Common ground reference for input and output, with quiescent current Id of 6 mA maximum.
3 OUTPUT power_out Regulated 5 V output (4.9 to 5.1 V at TJ = 25 °C for the AB version) with output current internally limited and up to 0.5 A.
