1、1 Jan. 2012 Rev. 2. 8BCD Semiconductor Manufacturing Limited 1A LOW DROPOUT LINEAR REGULATOR AZ1117 Data Sheet General Description The AZ1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output cur- rent. The AZ1117 series provides current limiting and ther- mal
2、 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-c
3、hip thermal shut- down provides protection against any combination of overload and ambient temperature that would create excessive junction temperature. The AZ1117 has an adjustable version, that can pro- vide the output voltage from 1.25V to 12V with only 2 external resistors. The AZ1117 series is
4、available in the industry standard SOT-223, SOT-89, TO-220-3, TO-252-2 (1), TO-252-2 (2), TO-252-2 (3), TO-252-2 (4) and TO-263-3 power packages.

These are stress ratings only, and functional operation of the device a
20、t 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.
21、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, JA, and the ambient temperature, TA. The maximum allowabl
22、e power dissipation at any ambient tem- perature is calculated using: PD(max)=(TJ(max) -TA)/JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
