General Description
The AP2302 linear regulator is designed to meet the
JEDEC specification SSTL-2 and SSTL-18 for termi-
nation of DDR-SDRAM. The regulator can sink or
source up to 3A current continuously, offers enough
current for most DDR applications. Output voltage is
designed to track the reference voltage within a 2%
(DDR I) and 3% (DDR II) tolerance for load regulation
while preventing shooting through on the output stage.
On-chip thermal limiting provides protection against a
combination of high current and ambient temperature
which would create an excessive junction temperature.
The AP2302, used in conjunction with series termina-
tion resistors, provides an excellent voltage source for
active termination schemes of high speed transmission
lines as those seen in high speed memory buses and
distributed backplane designs.
The AP2302 is available in SOIC-8, TO-252-5L and
TO-263-5L packages.
