78L05-MS from MSKSEMI, 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 | VOUT | power_out | Regulated output terminal; the 78L05-MS gives 5.0 V nominal (4.8 V to 5.2 V under test conditions, ±4% tolerance) with output current rated up to 100 mA. |
| 2 | GND | power_in | Ground terminal for the regulator. |
| 3 | VIN | power_in | Unregulated input terminal; the product features state input voltage up to 30 V, the absolute maximum input voltage is 32 V, and minimum input voltage is 8.5 V (max) with 8 V typical. |
