The CS8391 is a precision, dual 5V
micropower linear voltage regula-
tor. The switched primary output
(V
OUT1
) supplies up to 250mA
while the secondary (V
OUT2
) is
capable of supplying 100mA. Both
outputs have a maximum dropout
voltage of 600mV and low reverse
current. Quiescent current drain is
typically 150μA when supplying
100μA from each output.
The ENABLE input provides logic
level control of the primary output.
With the primary output disabled,
quiescent current drain is typically
100μA when supplying 100μA from
the secondary output.
The CS8391 is extremely robust
with protection provided for
reverse battery, short circuit, and
overtemperature on both outputs.
The CS8391 is available in a 5-lead
