A Product Line of Diodes Incorporated AZ1084C 5A LOW DROPOUT LINEAR REGULATOR Description Features The AZ1084C is a series of low dropout positive voltage regulators Low Dropout Voltage: 1.35V Typical at 5A with 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 trimmed bandgap reference and a current limiting circuit. Compatible with Low ESR Ceramic Capacitor Line Regulation (Adj Version): 0.015% (Typ) The AZ1084C is available in 1.5V, 1.8V, 2.5V, 3.3V and 5.0V Load Regulation (Adj Version): 0.1% (Typ) versions. The fixed versions integrate the adjust resistors. It is also Lead-Free Packages: TO263, TO263-2 available in an adjustable version which can set the output voltage Totally Lead-Free RoHS Compliant (Notes 1 & 2) with two external resistors. Lead-Free Packages, Available in Green Molding Compound: TO263, TO263-2, TO252-2 (3), TO252-2 (4), TO252-2 (5) The AZ1084C series is available in standard packages of TO263, Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) TO263-2, TO252-2 (3), TO252-2 (4) and TO252-2 (5).
