CS5111 1.4 A Switching Regulator with 5.0 V, 100 mA Linear Regulator with Watchdog, RESET and ENABLE The CS5111 is a dual output power supply integrated circuit. It contains a 5.0 V ± 2%, 100 mA linear regulator, a watchdog timer, a linear output voltage monitor to provide a Power On Reset (POR) and a 1.4 A current mode PWM switching regulator. The 5.0 V linear regulator is comprised of an error amplifier, reference, and supervisory functions. It has low internal supply current consumption and provides 1.2 V (typical) dropout voltage at maximum load current. The watchdog timer circuitry monitors an input signal (WDI) from the microprocessor. It responds to the falling edge of this watchdog signal.
