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. |
