Description

General part information

LT1585-1.5 Series

The LT1585-1.5/LT1585A-1.5 are low dropout, 3-terminal 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 limiting provides protection against any combination of overload 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.Output CurrentOutput Voltage OptionsLT1584, -3.3, -3.38, -3.45, -3.67AAdj, 3.3V, 3.38V, 3.45V, 3.6VLT1585, -3.3, -3.38, -3.45, -3.64.6AAdj, 3.3V, 3.38V, 3.45V, 3.6VLT1585A, LT1585A-3.35AAdj, 3.3VLT1585-1.5, LT1585A-1.54.6A/5AFixed 1.5VLT1587, -3.3, -3.45, -3.63AAdj. 3.3V, 3.45V, 3.6VLT1587-1.53AFixed 1.5VApplicationsGTL+ Power SupplyLow Voltage Logic SuppliesBattery-Powered Circuitry
