UZ1084G-3.3V-TN3-R

UTC Unisonic Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

UZ1084G-3.3V-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 reference pin for the fixed-voltage regulator, designated G in the ordering note (A/G: ADJ for adjustable, GND for fixed).
2 VOUT power_out Regulated output pin (designated O in the ordering note); for the UZ1084-33 3.3 V fixed version the output is 3.267 V to 3.333 V at 1% tolerance (3.234 V to 3.366 V at 2%) with IOUT=10mA, and the part is rated for up to 5 A output current.
3 VIN power_in Input supply pin (designated I in the ordering note); the absolute maximum DC input voltage is 15 V and the regulator requires 1.5 V ≤ (VIN−VOUT) ≤ 5.75 V for specified operation.
