The CS8129 is a precision 5V linear reg-
ulator capable of sourcing 750mA.
The
threshold voltage has been
lowered to 4.2V so that the regulator
can be used with 4V microprocessors.
The lower
threshold also per-
mits operation under low battery condi-
tions (5.5V plus a diode). The
delay time is externally programmed
using a discrete RC network. During
power up, or when the output goes out
of regulation,
low state for the duration of the delay.
This function is independent of the
input voltage and will function correct-
ly as long as the output voltage remains
at or above 1V. Hysteresis is included in
s
remains in the
the Delay and the
to improve noise immunity. A latching
discharge circuit is used to discharge
the delay capacitor when it is triggered
by a brief fault condition.
comparators
The regulator is protected against a
variety of fault conditions: i.e. reverse
battery, overvoltage, short circuit and
thermal runaway conditions. The regu-
lator is protected against voltage tran-
sients ranging from -50V to +40V. Short
circuit current is limited to 1.2A (typ).
The CS8129 is packaged in a 5 lead
TOD220 and a 16 lead surface mount
package.
