79L08K

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

79L08K from Shikues, 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 GND power_in Ground (common) terminal of the regulator, labelled GND on the SOT-89 pinout.
2 IN power_in Unregulated negative input terminal; the datasheet gives an input voltage limit of -30 V for Vo = -5 to -8 V.
3 OUT power_out Regulated negative output terminal, rated for output current up to 100 mA per the datasheet.
