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.
