UZ1085G-AD-TN3-R

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

UZ1085G-AD-TN3-R from UTC(Unisonic Tech), in a TO-252-2. 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 ADJ passive Adjust pin for the adjustable (AD) version, which sets the output voltage against the 1.25V reference (1.225V to 1.275V) and has an adjust pin current of 35µA typ and 120µA max.
2 VOUT power_out Regulated output delivering up to 3A, with a minimum load current of 10mA max and a 22µF output capacitor (COUT) used in the datasheet test conditions.
3 VIN power_in Input supply pin with an absolute maximum of 18V and a dropout voltage of 1.30V typ and 1.40V max at 3A.
