DESCRIPTION

The UTC LR18120 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 1.0V, 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 LR18120 can be low to 1.4V. There are two additional pin in the

LR18120. One is EN pin and the other is POK pin.

The UTC LR18120 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.
