LM78L10F from HTC Korea TAEJIN Tech, in a SOT-89-3. 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 | VOUT | power_out | Regulated 10V output of the LM78L10, rated for output current up to 100mA per the datasheet. |
| 2 | GND | power_in | Ground reference pin for the regulator; the datasheet gives no separate electrical limit for this pin. |
| 3 | VIN | power_in | Unregulated input for the LM78L10, with a recommended input range of 12.5V to 25V and an absolute maximum input voltage of 30V. |
