78D06LL-TN3-R

UTC(Unisonic Tech) · Linear Voltage Regulators (LDO) · TO-252-2(DPAK)

78D06LL-TN3-R from UTC(Unisonic Tech), in a TO-252-2(DPAK). 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 supply pin; the absolute maximum input voltage is 35 V (VIN).
2 GND power_in Ground reference pin of the regulator, shared between input and output return.
3 OUTPUT power_out Regulated fixed output pin, rated for output current up to 0.5 A (IOUT).
