UR5516A

LINEAR INTEGRATED CIRCUIT

3A BUS TERMINATION

REGULATOR

DESCRIPTION

The UTC UR5516A is designed to provide a regulated voltage

with bi-directional output current for DDR-SDRAM termination.

Current-limit work to limit the short-circuit current, on-chip thermal

shutdown provides protection against any combination of overload

that would create excessive junction temperature. The output voltage

tracks the voltage at V_REFpin. A resistor divider connected to V_IN,

GND and V_REFpins is used to provide a half voltage of V_INto V_REF

pin. In addition, an external ceramic capacitor and an open-drain

transistor connected to V_REFpin provides soft-start and shutdown

control respectively. Pulling and holding the V_REFto GND shuts off

the output. The output of UTC UR5516A will be high impedance

after being shut down by V_REFor thermal shutdown function.
