CS8156
12V, 5V Low Dropout Dual Regulator
with ENABLE
Description
Features
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.
