UCC283TDTR-3G3 Description
The UCC283TDTR-3G3 positive linear series pass voltage regulator is tailored for low-drop-out applications where low quiescent power is important. Fabricated with a BiCMOS technology ideally suited for low input-to-output differential applications, the UCC283TDTR-3G3 passes 3 A while requiring only 0.45 V of typical input voltage headroom (ensured 0.6-V dropout). These regulators include reverse voltage sensing that prevents current in the reverse direction. Quiescent current is always less than 650 μA. The UCC283TDTR-3G3 has been internally compensated in such a way that the need for a minimum output capacitor has been eliminated.
