CS8140/1  
5V, 500mA Linear Regulator  
with  
, and Watchdog  
Features  
RESET  
ENABLE,  
Description  
The CS8140 is a 5V Watchdog  
of three conditions: the watchdog sig-  
nal moves outside of its preset limits;  
the output voltage drops out of regula-  
tion by more than 4.5%; or the IC is in  
5V ± 4%, 500mA Output  
■
Regulator with protection circuitry and  
three logic control functions that allow  
a microprocessor to control its own  
power supply. The CS8140 is designed  
for use in automotive, switch mode  
power supply post regulator, and bat-  
tery powered systems.

its power up sequence. The  
sig-  
Watchdog  
nal is independent of VIN and reliable  
down to VOUT = 1V.  
RESET  
ENABLE  
In conjunction with the Watchdog, the  
ENABLE function controls the regula-  
torÕs power consumption. The CS8140Õs  
output stage and its attendant circuitry  
are enabled by setting the ENABLE  
lead high. The regulator goes into sleep  
mode (IOUT = 250µA) when the  
ENABLE lead goes low and the watch-  
dog signal moves outside its preset  
window limits. This unique combina-  
tion of control functions in the CS8140  
gives the microprocessor control over  
its own power down sequence: i.e. it  
gives the microprocessor the flexibility  
to perform housekeeping functions  
before it powers down.  
Low Dropout Voltage  
(1.25V @ 500mA)  
■
■
Basic regulator performance character-  
istics include a low noise, low drift, 5V  
± 4% precision output voltage with low  
dropout voltage (1.25V @ IOUT = 500mA)  
and low quiescent current (7mA @ IOUT  
= 500mA). On board short circuit, ther-  
mal, and overvoltage protection make it  
possible to use this regulator in particu-  
larly harsh operating environments.

The Watchdog logic function monitors  
an input signal (WDI) from the micro-  
processor or other signal source. When  
the signal frequency moves outside  
externally programmable window lim-  
signal is generated  
). An external capacitor  
(CDELAY) programs the watchdog win-  
dow frequency limits as well as the

The CS8141 has the same features as the
