供应3A总线终端稳压IC U5516
信息内容：3A BUS TERMINATIONREGULATORDESCRIPTIONThe UTC UR5516 is designed to provide a regulated voltage withbi-directional output current for DDR-SDRAM termination.Current-limit work to limit the short-circuit current, on-chip thermalshutdown provides protection against any combination of overloadthat would create excessive junction temperature. The output voltagetracks the voltage at VREF pin. A resistor divider connected to VIN,GND and VREF pins is used to provide a half voltage of VIN to VREFpin. In addition, an external ceramic capacitor and an open-draintransistor connected to VREF pin provides soft-start and shutdowncontrol respectively. Pulling and holding the VREF to GND shuts offthe output. The output of UTC UR5516 will be high impedance afterbeing shut down by VREF or thermal shutdown function.FEATURES* Provide bi-direction current- Sourcing or sinking current up to 3A* 1.25V/0.9V output for DDR I/II applications* Fast transient response* High output accuracy- ±20mv over load, V...
