Description

General part information

CS8129 Series

The CS8129 is a precision 5V linear regulator capable of sourcing 750mA. The RESETbar threshold voltage has been lowered to 4.2V so that the regulator can be used with 4V microprocessors. The lower RESETbar threshold also permits operation under low battery conditions (5.5V plus a diode). The RESETbar's delay time is externally programmed using a discrete RC network. During power up, or when the output goes out of regulation, RESETbar 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 1V. Hysteresis is included in the Delay and the RESETbar 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 -50V to +40V. Short circuit current is limited to 1.2A (typ).
