APL5337-茂達庫存

Source and Sink, 2A, Fast Transient Response Linear Regulatorregulated voltage with bi-direction output current for DDRSDRAM
termination voltage. The APL5337 integrates two
power transistors to source or sink load current up to 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 APL5337 is regulated to track the
voltage on VREF pin. A proper resistor divider connected
to VIN, GND, and VREF pins is used to provide a half
