A Product Line of Diodes Incorporated AZ1084 5A LOW DROPOUT LINEAR REGULATOR Description Features The AZ1084 is a series of low dropout positive voltage regulators with Low Dropout Voltage: 1.3V Typical at 5A a maximum dropout of 1.5V at 5A of load current. Current Limiting and Thermal Protection Output Current: 5A The series features on-chip thermal limiting which provides protection Current Limit: 6.5A against any combination of overload and ambient temperatures that Operating Junction Temperature Range: 0 to +125C would create excessive junction temperatures. It also includes a Line Regulation (Adj Version): 0.015% (Typical) trimmed band-gap reference and a current limiting circuit. Load Regulation (Adj Version): 0.1% (Typical) Lead-Free Packages: TO263, TO-263-2, TO-220-3, TO-252-2 (3), The AZ1084 is available in 1.5V, 1.8V, 2.5V, 3.3V and 5.0V versions. TO-252-2 (4), TO-252-2 (5) The fixed versions integrate the adjust resistors. It is also available in Totally Lead-Free RoHS Compliant (Notes 1 & 2) an adjustable version which can set the output voltage with two external resistors. Lead-Free Packages, Available in Green Molding Compound: TO263, TO-263-2, TO-220-3, TO-252-2 (3), TO-252-2 (4), TO- 252-2 (5) The AZ1084 series is available in standard packages of TO263, TO- Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) 263-2, TO-220-3, TO-252-2 (3), TO-252-2 (4) and TO-252-2 (5).
