Overview
UNISONIC TECHNOLOGIES CO.
, LTD LR18120 2A LOW DROPOUT REGULATOR WITH ENABLE  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.
 FEATURES * VIN as Low as 1.
