CS8151C  
5V, 100mA Low Dropout Linear Regulator  
with Watchdog, RESET, & Wake Up  
Description  
Features  
5V ±1% / 100 mA Output  
Voltage  
The CS8151C is a precision 5V, 100mA  
falling edge is issued on the wake-up  
signal line.  
micro-power voltage regulator with  
very low quiescent current (400µA typ-  
ical at 200µA load). The 5V output is  
accurate within ±1% and supplies 100  
mA of load current with a typical  
dropout voltage of 400mV.  
Microprocessor control logic includes  
Watchdog, Wake Up and RESET . This  
unique combination of low quiescent  
current and full microprocessor con-  
trol makes the CS8151C ideal for use in  
battery operated, microprocessor con-  
trolled equipment.  
Micropower Compatible  
Control Functions:  
RESET is independent of VIN and  
operates correctly to an output voltage  
as low as 1V. A RESET signal is issued  
in any of three situations. During  
power up the RESET is held low until  
the output voltage is in regulation.  
During operation if the output voltage  
shifts below the regulation limits, the  
RESET toggles low and remains low  
until proper output voltage regulation  
is restored. And finally, a RESET signal  
is issued if the regulator does not  
receive a Watchdog signal within the  
Wake Up period.

Low Dropout Voltage:  
400mV @ 100mA  
Low Sleep Mode Quiescent  
Current (400µA typ)  
Protection Features:  
Thermal Shutdown  
Short Circuit  
The CS8151C Wake Up function brings  
the microprocessor out of Sleep mode.  
The microprocessor in turn, signals its  
Wake Up status back to the CS8151C  
by issuing a Watchdog signal.  
74V Load Dump  
Reverse Transient (-50V)  
The RESET pulse width, Wake Up sig-  
nal frequency, and Wake Up delay  
time are all set by one external capaci-  
The Watchdog logic function monitors  
an input signal (WDI) from the micro-  
processor. The CS8151C responds to  
the falling edge of the Watchdog signal  
which it expects at least once during  
each wake-up period. When the cor-  
rect Watchdog signal is received, a  
tor CDelay.  
The regulator is protected against  
short circuit, over voltage, and thermal  
runaway conditions. The device can  
withstand 74 volt load dump tran-  
sients, making it suitable for use in  
automotive environments.
