TP78L05T3 from TECH PUBLIC, in a SOT89-3. 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 | OUT | power_out | Regulated 5V output (Vo 4.80-5.20V typ 5.0V at 25°C), up to 0.1A maximum output current, with a 0.1µF output capacitor Co in the typical application. |
| 2 | GND | power_in | Ground reference for the regulator, connected to the common return of the input and output capacitors. |
| 3 | IN | power_in | Input voltage pin, absolute maximum 30V, with a 0.33µF input capacitor C1 in the typical application. |
