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.
