The CS8161 is a 12V/5V dual out-
put linear regulator. The 12V ± 5%
output sources 400mA and the 5V
±2.0% output sources 200mA.
The on board ENABLE function
controls the regulatorÕs two out-
puts. When the ENABLE pin is
low, the regulator is placed in
SLEEP mode. Both outputs are dis-
abled and the regulator draws only
200nA of quiescent current.
The primary output, VOUT
1 is pro-
tected against overvoltage condi-
tions. Both outputs are protected
against short circuit and thermal
runaway conditions.
The CS8161 is packaged in a 5 lead
TOÐ220 with copper tab. The cop-
per tab can be connected to a heat
sink if necessary. It is also available
in a 16 lead SO wide package.
