2A LOW DROPOUT REGULATOR
WITH ENABLE
CMOS IC
„ 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 1.2V, 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.
