LM7805CS2

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-2

LM7805CS2 from HGSEMI, in a TO-263-2. 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 Vcc power_in Unregulated supply input to the regulator; the absolute maximum input voltage VIN is 35 V and the LM7805C input voltage range is 7.5 V to 35 V.
2 GND power_in Ground reference pin of the regulator.
3 OUT power_out Regulated output of the LM7805C, 4.80 V to 5.20 V at Io=0.5A, with a maximum output current IOM of 1.5 A.
