DESCRIPTIO
The LT^®1038 is a three terminal regulator which is capable
of providing in excess of 10A output current over 1.2V to
32V range. The device is packaged in a standard T0-3
power package and is plug-in compatible with industry
standard adjustable regulators, such as the LM117 and
LM138. Also, the LT1038 is a functional replacement for
the LM396.
In addition to excellent load and line regulations, the
LT1038 is fully protected by current limiting, safe area
protection and thermal shutdown. New current limiting
circuitry allows transient load currents up to 24A to be
supplied for 500µs without causing the regulator to cur-
rent limit and drop out of regulation during the transient.
On-chip trimming of initial reference voltage to ±0.8%
combined with 0.4% load regulation minimize errors in all
high current applications. Further, the LT1038 is manufac-
tured with standard bipolar processing and has Linear
Technology’s high reliability.
