5A LOW DROPOUT LINEAR REGULATOR
FSP1084
FEATURES
Low Dropout Voltage: 1.3V Typically at 5A Current Limiting and Thermal Protection Output Current: 5A Current Limit: 6.5A Operating Junction Temperature Range: 0 to 125 Line Regulation: 0.015%(Typical) Load Regulation: 0.2%(Typical)
GENERAL DESCRIPTION
The FSP1084 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 5A of load current. The series features on-chip thermal limiting which provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. It also includes a trimmed bandgap reference and a current limiting circuit. The FSP1084 is available in 1.5V, 1.8V, 2.5V, 3.3V and 5.0V versions. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set output voltage with two external resistors. The FSP1084 series is available in standard package of TO263-2L, TO220-3L and TO252-2L.
