UZ1085L-33-TN3-R

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

UZ1085L-33-TN3-R from UTC Unisonic Tech, in a TO-252-2(DPAK). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground / common return for the fixed-voltage regulator. Internal reference and error amplifier are referenced to this pin. Tab of the TO-252 is electrically connected to this pin (GND) for the fixed-output version.
2 VOUT power_out Regulated 3.3V output (typ 3.3V, min 3.234V, max 3.366V) capable of sourcing up to 3A. Requires a 22µF output capacitor for stability. Minimum load current 10mA typical.
3 VIN power_in Unregulated input supply. Operating range for the 3.3V fixed variant is 4.8V ≤ VIN ≤ 10.3V; absolute maximum 18V. Dropout voltage is typically 1.3V at IOUT=3A. A 22µF input capacitor is recommended.
