CS8129 - 5V 750mA Low Dropout Linear Regulator

Description

The CS8129 is a precision 5V linear regulator capable of sourcing 750mA.

The RESET threshold voltage has been lowered to 4.2V so that the regulator can be used with 4V microprocessors.

The lower RESET threshold also permits operation under low battery conditions (5.5V plus a diode).

CS8129 CS8129 5V, 750mA Low Dropout Linear Regulator with Lower RESET Threshold Description The CS8129 is a precision 5V linear regulator capable of sourcing 750mA. The RESET threshold voltage has been lowered to 4.2V so that the regulator can be used with 4V microprocessors. The lower RESET threshold also permits operation under low battery conditions (5.5V plus a diode). The RESET Õs delay time is externally programmed using a discrete RC network. During power up, 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 1V. Hysteresis is included in the Delay and the RESET comparators to improve noise immunity.
