78L12T from Foshan Blue Rocket Elec, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulated +12 V output. Typical 12 V (11.4-12.6 V) at Io up to 100 mA. Recommended output bypass capacitor Cout = 0.1 uF to ground. |
| 2 | GND | power_in | Common ground reference for the regulator. On SOT-89 this pin is also the tab/heat-spreader and should be connected to the ground plane for thermal dissipation. |
| 3 | IN | power_in | Unregulated input voltage. Absolute maximum Vi = 35 V; typical operating range approximately 14 V to 27 V for 12 V output. Recommended input bypass capacitor Cin = 0.33 uF to ground. |
