MAXIMUM 3A, ULTRA LOW DROPOUT REGULATOR WITH ENABLE

DESCRIPTION

The UTC L11831A/B/C is a positive voltage regulator with high

performance. It has low dropout voltage and low input voltage,

besides its output voltage can be fixed at 1V,1.05V, 1.2V, 1.5V,

1.8V, or 2.5V depending on internal feedback resistors or ADJ (not

connected to the ground) with external feedback resistors. There

are two additional pin in the UTC L11831A/B/C. One is EN pin and

the other is POK pin.

The UTC L11831A/B/C is specially made for applications with

low input voltage, low dropout voltage, and low output voltage

which is almost the same as the input voltage. Typical applications

include motherboards, notebooks, set top boxes, network cards

and peripheral cards.

FEATURES

* VDD voltage 5V

* Maximum 3A low-dropout voltage regulator

* High accuracy output voltage ±1.5%
