DESCRIPTION  
FEATURES  
The LT®1584/LT1585/LT1587 are low dropout three-  
terminal regulators with 7A, 4.6A and 3A output current  
capability, respectively. Design has been optimized for low  
voltage applications where transient response and mini-  
mum input voltage are critical. Similar to the LT1083/4/5  
family, it has lower dropout voltage and faster transient  
response. These improvements make it ideal for low volt-  
age microprocessor applications requiring a regulated  
2.5V to 3.6V output with an input supply below 7V.  
■
Fast Transient Response  
■
Guaranteed Dropout Voltage at Multiple Currents  
■
Load Regulation: 0.05% Typ

APPLICATIONS  
PentiumTM Processor Supplies  
■
PowerPCTM Supplies  
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 would create excessive junction temperatures.

The LT1585/LT1587 are available in both the through-hole  
and surface mount versions of the industry standard 3-pin  
TO-220 power package. The LT1584 is available in the  
through-hole 3-pin TO-220 power package.
