Application Information
A 1F (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 -25C. The capacitance may be increased without limit. A 1F capacitor (or larger) should be placed between VIN to GND.
