     Application Information

     A 1?ÌF (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 ?C25?æ. The capacitance may be increased without limit. A 1?ÌF capacitor (or larger) should be placed between VIN to GND.
