FEATURES  
DESCRIPTION  
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  
significantimprovementsintheseregulatorscomparedto  
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 difficult to damage. Internal current and power  
limitingcoupledwithtruethermallimitingpreventsdevice  
damage due to overloads or shorts, even if the regulator  
is not fastened to a heat sink.

On-Card Regulators  
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  
failuresexperiencedwithotherregulatorsthatreceiveonly  
standard electrical testing.
