Data Sheet
3A LOW DROPOUT LINEAR REGULATOR
AZ1085
General Description
Features
The AZ1085 is a series of low dropout positive voltage
regulators with a maximum dropout of 1.5V at 3A of
load current.
·
·
·
·
·
·
·
The series features on-chip thermal shutdown. It also
includes a bandgap reference and a current limiting circuit.
The AZ1085 is available in 1.5V, 1.8V, 2.5V, 3.3V,
5.0V and adjustable versions. The fixed versions integrate the adjust resistors. The adjustable version can
set the output voltage with two external resistors.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under"Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods may affect device reliability.
Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical
specifications do not apply when operating the device outside of its operating ratings. The maximum allowable
power dissipation is a function of the maximum junction temperature, TJ(max), the junction-to-ambient thermal
resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: 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.
