NJM78L09UA-TE1

JRC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

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.
