Caution: 1. The above connection diagram and constant will not guarantee successful operation. Perform thorough
evaluation using the actual application to set the constant.
2. Input capacitor (CIN): 1.0µF or more, Output capacitor (COUT): 1.0µF or more (tantalum capacitor)
3. A general series regulator may oscillate, depending on the external components selected. Check that no oscillation occurs
with the application using the above capacitor.
