Description

The AZ1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current.

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, which can provide the output voltage from 1.25V to 12V with only 2 external resistors.

The AZ1117 series is available in the industry standard SOT223, SOT89, TO220-3, TO252-2 (3), TO252-2 (4), TO252-2 (5) and TO263 power packages.

Features

 Low Dropout Voltage: 1.15V at 1A Output Current  Trimmed Current Limit  On-chip Thermal Shutdown  Three-terminal Adjustable or Fixed 1.2V, 1.5V, 1.8V, 2.5V, 2.85V,

3.3V, 5.0V

 Operation Junction Temperature: -40 to +125oC  Lead-Free Packages: SOT223, SOT89, TO220-3, TO252-2 (3),

TO252-2 (4), TO252-2 (5), TO263

 Totally Lead-Free; RoHS Compliant (Notes 1 & 2)

Applications

 PC Motherboard  LCD Monitor  Graphic Card  DVD-video Player  NIC/Switch  Telecom Equipment  ADSL Modem  Printer and other Peripheral Equipment

Absolute Maximum Ratings (Note 3)

Notes: 3. 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.

4. 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, T junction-to-ambient thermal resistance, θ calculated using: P regulator will go into thermal shutdown.
