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.
