Data Sheet 5A LOW DROPOUT LINEAR REGULATOR AZ1084 General Description Features The AZ1084 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. 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 125oC Line Regulation: 0.015% (Typical) Load Regulation: 0.2% (Typical) Applications The AZ1084 is available in 1.5V, 1.8V, 2.5V, 2.85V, 3.3V and 5.0V versions. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external resistors. · · · · · The AZ1084 series is available in standard packages of TO-263-2, TO-263-3, TO-220 and TO-252.
