UZ1086L-33-TN3-R

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

UZ1086L-33-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 GND power_in Ground pin for the fixed-voltage regulator; the ordering note defines G as GND for fixed regulators, and the MPN's -33 suffix denotes the 3.3V fixed version.
2 VOUT power_out Regulated output pin that delivers up to 1.5A output current, with 3.3V fixed output for this part.
3 VIN power_in Input supply pin; the absolute maximum input voltage is 7.5V and the electrical characteristics for the 3.3V version specify VIN up to 7V.
