CS8161
12 V, 5.0 V Low Dropout
Dual Regulator with ENABLE
The CS8161 is a 12 V/5.0 V dual output linear regulator. The
12 V ±5.0% output sources 400 mA and the 5.0 V ±2.0% output
sources 200 mA.
The on board ENABLE function controls the regulator’s two
outputs. When the ENABLE pin is low, the regulator is placed in
SLEEP mode. Both outputs are disabled and the regulator draws only
200 nA of quiescent current.
The primary output, VOUT1 is protected against overvoltage
conditions. Both outputs are protected against short circuit and
thermal runaway conditions.
The CS8161 is packaged in a 5 lead TO−220 with copper tab. The
copper tab can be connected to a heat sink if necessary.
