LM7805CTG

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

LM7805CTG from HANSCHIP semiconductor, 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 (Vi) power_in Unregulated input voltage; the absolute maximum is 35 V for output settings of 5 V to 18 V and 40 V for the 24 V output.
2 GND power_in Common ground and reference pin for the regulator; the datasheet gives no separate voltage or current limit for this pin.
3 OUT (Vo) power_out Regulated 5 V output for the LM7805, rated for output currents up to 1.0 A (Po < 15 W) with Vo typically 5.0 V (4.8 V to 5.2 V at Tj = 25 °C).
