Preliminary
MAXIMUM 3A, ULTRA LOW
DROPOUT REGULATOR WITH
ENABLE
 DESCRIPTION
The UTC L11831A/B 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. The
input voltage of UTC L11831A/B can be low to 1.4V. There are two
additional pin in the UTC L11831A/B. One is EN pin and the other
is POK pin.
The UTC L11831A/B 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
* VIN as low as 1.4V and VDD voltage 5V
* Maximum 3A low-dropout voltage regulator
* High accuracy output voltage ±1.5%
* When disable VO pull low resistance
* Internal over current and over temperature protection
