3A Negative Adjustable
Regulator
Description
The LT®1033 negative adjustable regulator will deliver
up to 3A output current over an output voltage range of
–1.2V to –32V. Linear Technology has made significant
improvements in these regulators compared to previous
devices, such as better line and load regulation, and a
maximum output voltage error of 1%.
The LT1033 is easy to use and difficult to damage. Internal
current and power limiting as well as true thermal limiting
prevents device damage due to overloads or shorts, even
if the regulator is not fastened to a heat sink.
Maximum reliability is attained with Linear Technology’s
advanced processing techniques combined with a 100%
burn-in in the thermal limit mode. This assures that all
device protection circuits are working and eliminates field
failures experienced with other regulators that receive only
standard electrical testing.
