5A Low Dropout Fast Response

Positive Adjustable and Fixed

Voltage Regulators

The LT1585A is a low dropout 3–terminal voltage regulator with 5A output

current capability.

Design has been optimized for low voltage applications where transient

response and minimum input voltage are critical. This voltage regulator

features a low dropout voltage and fast transient response. These

improvements make them ideal for low voltage microprocessor applications

requiring a regulated 2.5V to 3.6V output with an input supply below 7V.

Current limits is trimmed to ensure specified output current and controlled

short–circuit current. On–chip thermal limiting provides protection against

any combination of overload that would create excessive junction

temperatures. The LT1585A is available in the industry standard 3–pin

TO–220 and D2PAK power package.

Features

• Fast Transient Response

• Guaranteed Dropout Voltage at Multiple Currents
