FEATURES  
DESCRIPTIO  
Guaranteed 1% Initial Tolerance  
The LT®138A series of adjustable regulators provide 5A  
outputcurrentoveranoutputvoltagerangeof1.2Vto32V.  
The internal voltage reference is trimmed to less than 1%,  
enabling a very tight output voltage. In addition to excel-  
lent line and load regulation, with full overload protection,  
the LT138A incorporates new current limiting circuitry  
allowing large transient load currents to be handled for  
short periods. Transient load currents of up to 12A can be  
supplied without limiting, eliminating the need for a large  
output capacitor.

The LT138A is an improved version of the popular LM138  
with improved circuit design and advanced process tech-  
niques to provide superior performance and reliability.  
The graph below shows the significant improvement in  
output voltage tolerance achieved by using the LT138A or  
LT338A.
