illustrate

The AZ1084 is a series of low dropout positive voltage regulators with a maximum voltage drop of 1.5V at 5A load current.

The family features on-chip thermal limiting to prevent any combination of overload and ambient temperature that would create excessive junction temperatures. It also includes a trimmed bandgap reference and a current limit circuit.

The AZ1084 is available in 1.5V, 1.8V, 2.5V, 3.3V and 5.0V versions. Fixed integrated adjustment resistor. It is also available in an adjustable version that can set the output voltage with two external resistors.

The AZ1084 series is available in TO263 , TO-263-2, TO-220-3, TO-252-2(3), TO-252-2(4) and TO-252-2(5) standard packages.

Absolute Maximum Ratings (Note 4)

notes

1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are pressure ratings only, and the functional operation of the equipment at these or any other conditions, other than those shown in "Recommended Operating Conditions". Long-term exposure to Absolute Maximum Ratings may affect device reliability.

5. Absolute Maximum Ratings indicate the limits at which parts may be damaged. When operating equipment beyond its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature TJ(max) and the junction-to-ambient thermal resistance θJA and the ambient temperature TA. Calculate the maximum allowable power dissipation usage at any ambient temperature: PD(max)=(TJ(max)-TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature and the regulator will go into thermal shutdown.
