Description
General part information
UCC283 Series
The UCC283–3/–5/–ADJ family of positive linear series pass voltage regulators are 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 UCC283–5 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. These devices have been internally compensated in such a way that the need for a minimum output capacitor has been eliminated.
UCC283–3 and UCC283–5 versions are in 3-lead packages and have preset outputs at 3.3 V and 5.0 V respectively. The output voltage is regulated to 1.5% at room temperature. The UCC283–ADJ version, in a 5-lead package, regulates the output voltage programmed by an external resistor ratio.
