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