L7818CV

MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

L7818CV from MSKSEMI, in a TO-220. 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 IN power_in Unregulated input pin; the datasheet gives an absolute maximum input voltage of 35 V and specifies regulation for Vi from 21 V to 33 V.
2 GND power_in Ground pin of the three-terminal regulator, listed as pin 2 in the pin assignment.
3 OUT power_out Regulated 18 V output (Vo 17.1 V to 18.9 V for Vi 21 V to 33 V and Io 5 mA to 1 A) with a maximum output current IOM of 1.5 A.
