The CS8156 is a low dropout 12V/5V

dual output linear regulator. The 12V

± 5% output sources 750mA and the 5V

±2.0% output sources 100mA.

The on board ENABLE function con-

trols the regulatorÕs two outputs. When

the ENABLE lead is low, the regulator

is placed in SLEEP mode. Both outputs

are disabled and the regulator draws

only 200nA of quiescent current.

The regulator is protected against over-

voltage conditions. Both outputs are

protected against short circuit and ther-

mal runaway conditions.

The CS8156 is packaged in a 5 lead

TOÐ220 with copper tab. The copper

tab can be connected to a heat sink if

necessary.
