78L08MG-AB3-R from UTC Unisonic Tech, in a SOT-89. 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 | OUTPUT | power_out | Regulated fixed output voltage (8V for the 78L08 variant), supplying up to 200mA output current. |
| 2 | GND | power_in | Ground reference pin for the regulator; the datasheet gives no further electrical limit for this pin. |
| 3 | INPUT | power_in | Unregulated supply input, rated at 30V maximum for 5V to 9V output variants (the 8V part) and 35V maximum for 12V to 24V variants. |
