BL79L05 from GME(银河微电), 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 | GND | power_in | Ground reference pin (labelled G on the SOT-89 drawing), common to the input and output capacitors. |
| 2 | IN | power_in | Negative input voltage pin (labelled I), absolute maximum -35 V, with a 0.33 µF input capacitor recommended. |
| 3 | OUT | power_out | Regulated negative output (labelled O), -5.0 V typical (-4.8 to -5.2 V) for BL79L05, with a 0.1 µF output capacitor recommended. |
