The CS5112 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.
