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. |
