Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution is highly recommended.
Note 3. The device is not guaranteed to function outside its operating conditions.
Note 4. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of
JEDEC 51-3 thermal measurement standard.
Application Information
A 1μF (or larger) capacitor is recommended between VOUT and GND for stability. The part may oscillate without the
capacitor. Any type of capacitor can be used, but not Aluminum electrolytes when operating below –25°C. The capacitance
may be increased without limit.
A 1μF capacitor (or larger) should be placed between VIN to GND.
