DESCRIPTIO

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.

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.
