DESCRIPTION  
FEATURES  
The LT®1587-1.5 is a low dropout 3-terminal regulator  
with a fixed 1.5V output voltage and 3A output current  
capability. The design is optimized for low voltage applica-  
tionswheretransientresponseandminimuminputvoltage  
are critical. Similar to the LT1085, it has lower dropout and  
faster transient response. These improvements make it  
ideal for low voltage microprocessor applications, espe-  
cially as the regulator in an Intel Pentium Pro processor

Current limit is trimmed to ensure specified output current  
and controlled short-circuit current. On-chip thermal lim-  
iting provides protection against any combination of over-  
load that creates excessive junction temperatures.  
The LT1587-1.5 is available in both the through-hole and  
surface mount versions of the industry standard 3-pin  
TO-220 power package.
