GTL+ Regulators
DESCRIPTIO
The LT
®
1585-1.5/LT1585A-1.5 are low dropout, 3-termi-
nal regulators with 4.6A and 5A output current capability
respectively, and a fixed 1.5V output voltage. The designs
are optimized for low voltage applications where transient
response and minimum input voltage are critical. Similar to
the LT1084, they have lower dropout and faster transient
response. These improvements make them ideal for low
voltage microprocessor applications, especially as the
regulator in an Intel processor GTL+ supply.
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 LT1585-1.5/LT1585A-1.5 are available in the through-
hole 3-pin TO-220 power package and 3-pin plastic DD.
, LTC and LT are registered trademarks of Linear Technology Corporation.
