The CS8121 is a 5V, 1A precision linear
regulator with two microprocessor
compatible control functions and pro-
tection circuitry included on chip. The
composite NPN-PNP output pass tran-
sistor assures a lower dropout voltage
(1.2V @ 1A) without requiring exces-
sive supply current (4mA).
The CS8121s two logic control func-
tions make this regulator well suited to
applications requiring microprocessor-
based control at the board or module
level.
controls the output
stage. A high voltage (>2.9V) on
the
lead turns off the regula-
tors pass transistor and sends the IC
into Sleep mode where it draws only
250μA.

The CS8121 design optimizes supply
rejection by switching the internal
bandgap reference from the supply
input to the regulator output as soon as
the nominal output voltage is achieved.
Additional on chip filtering enhances
rejection of high frequency transients
on all external leads.
The CS8121 is fault protected against
short circuit, over voltage and thermal
runaway conditions.
