CS8140 - 5V/ 500mA Linear Regulator with ENABLE/ / and Watchdog RESET

Description

The CS8140 is a 5V Watchdog Regulator with protection circuitry and three logic control functions that allow a microprocessor to control its own power supply.

The CS8140 is designed for use in automotive, switch mode power supply post regulator, and battery powered systems.

CS8140/1 CS8140/1 5V, 500mA Linear Regulator with ENABLE, RESET , and Watchdog Description The CS8140 is a 5V Watchdog Regulator with protection circuitry and three logic control functions that allow a microprocessor to control its own power supply. The CS8140 is designed for use in automotive, switch mode power supply post regulator, and battery powered systems. Basic regulator performance characteristics include a low noise, low drift, 5V ± 4% precision output voltage with low dropout voltage (1.25V @ IOUT = 500mA) and low quiescent current (7mA @ IOUT = 500mA). On board short circuit, thermal, and overvoltage protection make it possible to use this regulator in particularly harsh operating environments.
