 APPLICATION INFORMATION
A 10μF (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 electrolytics when operating below -25â. The
capacitance may be increased without limit.
A 1μF capacitor (or larger) should be placed between VIN to GND.
