SA57003
Five-output composite voltage regulator

GENERAL DESCRIPTION
The SA57003 is a very low noise, low dropout voltage regulator with
three independent preset outputs from 2.0 V to 5.0 V and two
dependent outputs regulated from 2.82 V up to V
OUT3
. The output
current is the same for all three independent outputs 1, 2, 3 and
each output is capable of supplying 200 mA. The other two
dependent outputs 4, 5 are capable of supplying current up to
185 mA and 195 mA, respectively. Additionally, the SA57003 has an
independent ON/OFF input pin for each output to allow individual
subcircuits to be turned off when not needed, making the device
very useful for applications where power conservation is important.
The independent output voltage regulators V
OUT1
, V
OUT2
, and
V
OUT3
have a common input voltage pin, V
IN
. The dependent output
voltage regulators, V
OUT4
and V
OUT5
have a common input voltage
pin, V
OUT3
.
The SA57003 regulator is offered in the TSSOP16 package.
