General Description<\/h3>\n\n\n\n

The EC2960\/EC2960A linear regulator is designed to provide a regulated voltage with bi-direction output current
for DDRSDRAM termination voltage.
The EC2960 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 EC2960\/EC2960A 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
EC2960\/EC2960A will be high impedance after being shutdown by VREF or the thermal shutdown function.<\/p>\n\n\n\n
