CS8371
8V/1A, 5V/250mA Dual Regulator with
Independent Output Enables and NoCapª
Description
The CS8371 is a 8V/5V dual output
linear regulator. The 8V ±5% output
sources 1A, while the 5V ±5% out-
put sources 250mA. Each output is
controlled by its own ENABLE
lead. Setting the ENABLE input
high turns on the associated regula-
tor output. Holding both ENABLE
inputs low puts the IC into sleep
mode where current consumption
is less than 10µA.
The regulator is protected against
overvoltage, short-circuit and ther-
mal runaway conditions. The
device can withstand 45V load
dump transients making suitable
for use in automotive environ-
ments. CherryÕs proprietary
NoCapª solution is the first tech-
nology which allows the output to
be stable without the use of an
external capacitor.
The CS8371 is available in a 7 lead
TO-220 package with copper tab.
The tab can be connected to a
heatsink if necessary.
