LR7805

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

LR7805 from LRC, 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 Input power_in Unregulated input voltage to the regulator; the datasheet's absolute maximum input voltage is 35 V for 5 V to 18 V outputs (40 V for the 24 V output).
2 GND power_in Common ground reference pin for the regulator, shared by input and output.
3 Output power_out Regulated 5 V output, rated for output current up to 1 A with short-circuit current limiting and thermal overload shutdown protection.
