The CXEP3472/CXEP3472A linear regulator is designed to provide a regulated voltage with bi-direction output current for DDRSDRAM termination voltage. The CXEP3472 integrates two power transistors to source or sink load current up to 1.5A/2A. It also features internal soft-start, current-limit, thermal shutdown and enable control functions into a single chip. The internal soft-start controls the rising rate of the output voltage to prevent inrush current during start-up. The current-limit circuit detects the output current and limits the current during short-circuit or current overload conditions. The on-chip thermal shutdown provides thermal protection against any combination of overload that would create excessive junction temperatures. The output voltage of CXEP3472/CXEP3472A is regulated to track the voltage on VREF pin. An proper resistor divider connected to VIN, GND, and VREF pins is used to provide a half voltage of VIN to VREF pin. In addition, connect an external ceramic capacitor and a open-drain transistor to VREF pin for external soft-start and shutdown control. Pulling and holding the voltage on VREF below the enable voltage threshold shuts down the output. The output of CXEP3472/CXEP347A will be high impedance after being shut down by VREF or the thermal shutdown function.
