NJM78L08UA-TE1

JRC · Linear Voltage Regulators (LDO) · SOT-89

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.
