L78M24ACDT-TR from STMicroelectronics, in a 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 | Regulator input; DC input voltage must not exceed 40 V for the 24 V version, with 27 to 38 V specified for the L78M24 electrical characteristics and a 0.33 µF bypass capacitor recommended close to the pin. |
| 2 | GND | power_in | Ground reference, shown in Figure 2 as the DPAK mounting tab with the middle lead cut short. |
| 3 | OUTPUT | power_out | Regulated 24 V output (23.5 to 24.5 V at 25 °C for the A version) with output current up to 0.5 A and internal current limiting. |
