BL78L10 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 | VO | power_out | Regulated 10 V output (9.6 V min, 10.4 V max at Tj=25°C), with a 0.1 µF output capacitor shown in the application circuit and up to 100 mA maximum output current. |
| 2 | GND | power_in | Ground reference for input and output, connected to the common ground in the application circuit. |
| 3 | VI | power_in | Unregulated input voltage, absolute maximum 35 V for the 78L10, with a 0.33 µF input capacitor shown in the application circuit. |
