CS8127  
5V Linear Controller/Driver  
Features  
Description  
The CS8127 contains all the necessary  
lead allows remote sensing of the output  
voltage for improved regulation.  
■ 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 CS8127 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.  
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 CS8127 is compatible  
with a wide variety of external transis-  
tors, allowing flexibility for thermal,  
space, and cost management.  
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  
become unregulated. This function is  
independent of the input voltage and  
will function correctly with an output  
voltage as low as 1V. Hysteresis is  
included in both the reset and delay  
comparators for noise immunity and to  
prevent oscillations. A latching dis-  
charge circuit is used to discharge the  
delay capacitor, even when triggered by  
a relatively short fault condition. This  
■ 60V Peak Transient  
Capability  
■ Internal Thermal  
Overload Protection  
■ 3% Output Accuracy  
■ Active RESET  
■ Noise Immunity  
■ On Chip EMC Hardening  
Protection Incorporated  
■ Externally Set Current  
Limit  
The CS8127 includes thermal shutdown,  
externally programmable current limit,  
and over-voltage shutdown, making it  
suitable for use in automotive and  
switching regulator post regulator appli- circuit improves upon the commonly  
cations. An optional external RC filter  
added to the CS8127 supply lead pro-  
vides EMC hardening in addition to the  
on-chip EMC hardening. The SENSE  
used SCR structure by providing  
improved noise immunity and full  
capacitor discharge (0.2V typ).
