NJM78L08UA-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 positive output; for the NJM78L08 the datasheet gives 7.6 V to 8.4 V (typ. 8.0 V) at VIN=14 V, IO=40 mA, with guaranteed 100 mA output current if adequate heat sinking is provided. |
| 2 | GND | power_in | Common ground and reference pin; the input capacitor CIN and output capacitor CO should each be connected between GND and VIN or VOUT respectively by the shortest possible path. |
| 3 | IN | power_in | Unregulated input supply; the datasheet recommends CIN of 0.33 µF or larger placed between GND and VIN as close as possible to prevent oscillation. |
