CS8129
5.0 V, 750 mA Low Dropout
Linear Regulator with
Lower RESET Threshold
The CS8129 is a precision 5.0 V linear regulator capable of sourcing
750 mA. The RESET threshold voltage has been lowered to 4.2 V so
that the regulator can be used with 4.0 V microprocessors. The lower
RESET threshold also permits operation under low battery conditions
(5.5 V plus a diode). The RESET’s delay time is externally
programmed using a discrete RC network. During powerup, or when
the output goes out of regulation, RESET remains in the low state for
the duration of the delay. This function is independent of the input
voltage and will function correctly as long as the output voltage
remains at or above 1.0 V. Hysteresis is included in the Delay and the
RESET comparators to improve noise immunity. A latching discharge
circuit is used to discharge the delay capacitor when it is triggered by a
brief fault condition.
The regulator is protected against a variety of fault conditions: i.e.
reverse battery, overvoltage, short circuit and thermal runaway
conditions. The regulator is protected against voltage transients ranging
from −50 V to +40 V. Short circuit current is limited to 1.2 A (typ).
The CS8129 is packaged in a 5 lead TO−220 and a 16 lead surface
mount package.
