AZ1084 is a series of 5A low dropout positive voltage regulators with a maximum dropout of 1.5V at 5A of load current, from BCD Semiconductor Manufacturing Limited. The series features on-chip thermal limiting which pro- vides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. It also includes a trimmed band- gap reference and a current limiting circuit. 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.
