UA78L15ACPK from Texas Instruments, 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 | OUTPUT | power_out | Regulated output voltage nominally 15 V; output voltage 14.4 V to 15.6 V at TJ = 25°C and IO = 1 mA to 40 mA with input voltage 17.5 V to 30 V; maximum output current 100 mA; use 0.1 µF bypass capacitor. |
| 2 | COMMON | power_in | Ground reference pin providing return path for input and output circuits. |
| 3 | INPUT | power_in | Input supply voltage pin accepting 17.5 V to 30 V DC with quiescent current 4.6 mA to 6.5 mA at TJ = 25°C; use 0.33 µF bypass capacitor. |
