NJM78L09UA-TE1 from JRC, 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 | OUT | power_out | Regulated 9 V output with 9.0 V typical and 8.55 V to 9.45 V limits at VIN=15 V and IO=40 mA, guaranteed for 100 mA output current when adequate heat sinking is provided. |
| 2 | GND | power_in | Common ground return for the regulator, to which the CIN and CO capacitors should be connected by the shortest path. |
| 3 | IN | power_in | Unregulated input with an absolute maximum of 30 V for the 78L09A, and an input capacitor of at least 0.33 µF should be connected between IN and GND as close as possible. |
