AP1128
„ General Description
AP1128 is a linear regulator designed as a
cost-effective solution for active termination of DDR
SDRAM. The converting voltage range is from 1.6V
to 6V into a desired output voltage, which is
adjusted by two external resistors. The current
sourcing and sinking capability of the regulator is up
to 1.5A/3A while the output voltage within 2%/3%.
This device provides on-chip thermal shutdown and
current limit functions for circuit tolerance of the
output fault conditions. SO-8 and TO-252-5L
packages are available for all commercial and
industrial surface mount applications.
