CS8120
5V, 300mA Linear Regulator with
RESET and ENABLE
Description
Features
The CS8120 is a 5V, 300mA precision
linear regulator with two microproces-
sor compatible control functions and
protection circuitry included on chip.
The composite NPN-PNP output pass
transistor assures a lower dropout volt-
age (1V @ 200mA) without requiring
excessive supply current (2.5mA).
The CS8120Õs two logic control func-
tions make this regulator well suited to
applications requiring microprocessor-
based control at the board or module
level. ENABLE controls the output
stage. A high voltage (>2.9V) on the
ENABLE lead turns off the regula-
torÕs pass transistor and sends the IC
into Sleep mode where it draws only
250µA. The RESET function sends a
RESET signal when the IC is power-
ing up or whenever the output voltage
moves out of regulation. The RESET
signal is valid down to VOUT = 1V.
The CS8120 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 CS8120 is fault protected against
short circuit, over voltage and thermal
runaway conditions.
