79D05G-TN3-R

UTC(Unisonic Tech) · Linear Voltage Regulators (LDO) · TO-252

79D05G-TN3-R from UTC(Unisonic Tech), in a TO-252. 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 GND power_in Ground pin of the three-terminal negative regulator, assigned as G in the ordering pin code table.
2 INPUT power_in Negative unregulated input voltage; absolute maximum input is -35V for VOUT -5 to -18V and -40V for VOUT -20 to -24V.
3 OUTPUT power_out Regulated negative output, -5V for the 79D05, rated for up to 0.5A output current with internal current limiting and thermal shut-down.
