LT1585-1.5/LT1585A-1.5

Fixed 1.5V, 4.6A and 5A

Low Dropout, Fast Response

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.
