Source and Shink 1.5A/2A Fast Transient

Response Line Regulator

EC2960

General Description

Features

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.

Compliant)

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.
