EC2960 Datasheet | E-CMOS

Source and Shink 1.5A/2A Fast Transient Response Line Regulator 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 bination 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. - Provide Bi-direction Output Currents - Sourcing and Sinking Current up to 1.5A/2A Built-in Soft-Start - Power-On-Reset Monitoring on VCNTL and VIN pins - Fast Transient Response - Stable with Ceramic Output Capacitors ±20m V High System Output Accuracy over Load and Temperature Ranges - Adjustable Output Voltage by External Resistors - Current-Limit Protection - On-Chip Thermal Shutdown - Shutdown for Standby or Suspend Mode - Simple SOP-8 with Exposed Pad(SOP8-EP) Packages - Lead Free and Green Devices Available(Ro HS pliant) Applications - DDRII/III SDRAM Termination Voltage - Motherboard...
