CS8126,-1,-2  
5V, 750mA Low Dropout Linear Regulator  
with Delayed RESET  
Description  
Features  
The CS8126 is a low dropout, high cur-  
rent 5V linear regulator. It is an  
state for the duration of the delay.  
Types of errors include short circuit,  
low input voltage, overvoltage shut-  
down, thermal shutdown, or others that  
cause the output to become unregulat-  
ed. This function is independent of the  
input voltage and will function correct-  
ly with an output voltage as low as 1V.  
Hysteresis is included in both the reset  
and Delay comparators for enhanced  
noise immunity. A latching discharge  
circuit is used to discharge the Delay  
capacitor, even when triggered by a rel-  
atively short fault condition. This circuit  
improves upon the commonly used  
SCR structure by providing full capaci-  
tor discharge (0.2V type).  
Low Dropout Voltage  
(0.6V at 0.5A)  
improved replacement for the CS8156.  
Improvements include higher accuracy,  
tighter saturation control, better supply  
rejection, and enhanced RESET circuit-  
ry. Familiar PNP regulator features  
such as reverse battery protection, over-  
voltage shutdown, thermal shutdown,  
and current limit make the CS8126 suit-  
able for use in automotive and battery  
operated equipment. Additional on-  
chip filtering has been included to  
enhance rejection of high frequency  
transients on all external leads.
