L7810CV

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

L7810CV 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 voltage; the datasheet's absolute maximum input voltage Vi is 35 V, and regulation to 10 V is specified for 10.5 V ≤ Vi ≤ 23 V.
2 GND power_in Common ground terminal for the regulator, which the datasheet lists as the second terminal of the three-terminal positive regulator.
3 OUT power_out Regulated 10 V output with a maximum output current IOM of 1.5 A.
