LM79L08F 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 | GND | power_in | Ground reference pin of the regulator (datasheet pin table lists it as GND for both TO-92 and SOT-89). |
| 2 | VIN | power_in | Negative input voltage; for the LM79L08 the recommended input range is -10.5 V to -23 V, with an absolute maximum of -30 V for the LM79L05 to LM79L09 group. |
| 3 | VOUT | power_out | Regulated negative output voltage (-8 V nominal for the LM79L08), capable of delivering up to 100 mA of output current. |
