The LX8941 is an adjustable, low
dropout regulator rated for more than
1A of output current. It can regulate
with as low as 0.8V headroom between
the input and output voltages, at 1A
output current, thus minimizing power
dissipation. In addition, it can be used
in applications where worst case
supplies require a low input-output
differential to maintain regulation. This
feature makes it ideal for some
processor applications that require 4V
operation from a 5V supply. In
addition, the LX8941 provides an on/off
switch that reduces the IC quiescent
current when activated, making it ideal
for battery operated applications.
