3A LOW DROPOUT LINEAR REGULATOR
General Description
Features
Data Sheet
AZ1085
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 cir-
cuit.
The AZ1085 is available in 1.5V, 1.8V, 2.5V, 3.3V,
5.0V and adjustable versions. The fixed versions inte-
grate the adjust resistors. The adjustable version can
set the output voltage with two external resistors.
The AZ1085 series is available in standard packages of
TO-263-2, TO-263-3, TO-220-3, TO-252-2 (1), TO-
252-2 (2), TO-252-2 (3) and TO-252-2 (4).
· Low Dropout Voltage: Typical 1.3V at 3A
· Current Limiting and Thermal Protection
· Output Current: 3A
· Current Limit: 4.5A
· Operating Junction Temperature: 0 to 125oC
· Line Regulation: 0.015% (Typical)
· Load Regulation: 0.1% (Typical)
Applications
· High Efficiency Linear Regulators
· Battery Charger
· Post Regulation for Switching Supplies
· Microprocessor Supply
· Mother Board Power Supplies
· DVD-Video Player
· Telecom Equipment
· Set Top boxes and Web Boxes Modules' Supply
