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.
