CS8128  
5V Linear Controller/Driver  
Features  
Description  
The CS8128 contains all the necessary  
lead allows remote sensing of the output  
ꢀ Externally Set Delay for  
control circuitry to implement a 5V lin-  
ear regulator. An external pass device is  
used to produce superior performance  
compared to conventional monolithic  
regulators. The CS8128 with a TIP42  
PNP transistor typically provides a  
100mV dropout voltage at 500mA,  
increasing to 350mV at 3A. Quiescent  
current at 500mA is only 5mA.  
voltage for improved regulation.  
Reset  
An active microprocessor RESET func-  
tion is included on-chip with externally  
programmable delay time. During  
power-up, or after detection of any error  
in the regulated output, the RESET lead  
will remain in the low state for the dura-  
tion of the delay. Types of errors include  
short circuit, low input voltage, over-  
voltage shutdown, thermal shutdown,  
or others that cause the output to

ꢀ Noise Immunity  
Monolithic regulators cannot approach  
these figures because their power tran-  
sistors do not provide the high beta and  
excellent saturation characteristics at  
high currents. The CS8128 is compatible  
with a wide variety of external transis-  
tors, allowing flexibility for thermal,  
space, and cost management.

independent of the input voltage and  
will function correctly with an output  
voltage as low as 1V. Hysteresis is

comparators for noise immunity and to

a relatively short fault condition. This
