LM7805T

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

LM7805T from HGSEMI, in a TO-220-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Unregulated positive input voltage. Operating range 7.5V to 35V for 5V output; absolute max VIN = 35V. Recommend a 0.33uF bypass capacitor to GND close to the pin.
2 GND power_in Common ground reference for input and output. Also serves as the thermal path via the TO-220 tab (tab is electrically connected to GND).
3 OUT power_out Regulated +5.0V output (4.80V to 5.20V). Delivers up to 1.2A. Recommend a 0.1uF ceramic (plus optional 10uF bulk) capacitor to GND for stability.
