Multiple output low noise, low dropout linear regulator

GENERAL DESCRIPTION
The SA57005 is a very low dropout, low noise composite voltage
regulator with three fixed independent outputs. The output voltages
are preset to 2.5 V, 2.8 V and 3.0 V having a common input voltage
pin V
IN
. Two ON/OFF switches allow V
o1
and V
o2
/V
o3
to be turned
off when not needed, thus conserving power. Also, three regulators
in one package save board space, which is critical in
microprocessor systems.
Designed for battery-powered and portable applications the
SA57005 achieves unequalled performance in all specifications
such as low supply-current, low dropout voltage, low power
consumption, small size, fast dynamic response to line and load,
precision output and so on. Each of these regulators consists of an
internal voltage reference, an error amplifier, resistors, and control
switch. The SA57005 is housed in a VSOP-8A 8-lead package.
