78L08-150

UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

78L08-150 from UMW, in a SOT-89-3. 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 OUTPUT power_out Regulated output of the 78L08 (8V nominal, 7.92V to 8.08V), rated for up to 150mA with thermal overload protection and short-circuit current limiting.
2 GND power_in Common ground return for the regulator, to be connected to the system ground.
3 INPUT power_in Unregulated supply input; the datasheet gives an absolute maximum input voltage of 35V for output voltages 3.3V to 18V, which includes the 8V version.
