The LT ? 137A/LT337A negative adjustable regulators will
deliver up to 1.5A output current over an output voltage
range of –1.2V to –37V. Linear Technology has made
signi?cant improvements in these regulators compared to
previous devices, such as better line and load regulation,
and a maximum output voltage error of 1%.
APPLICATIONS
Every effort has been made to make these devices easy

to use and dif?cult to damage. Internal current and power
limiting coupled with 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 ?eld
failures experienced with other regulators that receive only
standard electrical testing.
