5V, 750mA Low Dropout Linear Regulator
with Delayed RESET
Description
The CS8126 is a low dropout, high cur-
rent 5V linear regulator. It is an
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.
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 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).
Note:The CS8126 is lead compatible
with the LM2925, TLE4260, L4947,
LM2927, and LM2926.
