1A LOW DROPOUT LINEAR REGULATOR AZ1117

General Description

The AZ1117 is a series of low dropout three-term inal regulators with a dropout of 1.15V at 1A output cu rrent.

The AZ1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 5.0V and adjustable versions or 2% for 1.2V version. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature.

The AZ1117 has an adjustable version, that can provide the output voltage from 1.25V to 12V with only 2 external resistors.

The AZ1117 series is available in the industry standard SOT-223, SOT-89-3, TO-220-3, TO-252-2 (1) and TO263-3 power packages.

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 impli ed. Exposure to "Absolute Maximum Ratings" for extended periods may affect device reliability. Note 2: Absolute maximum ratings indicate limits beyond which damage to the componen t may occur.
