Caution The above connection diagram and constant will not guarantee successful operation.
Perform thorough evaluation using the actual application to set the constant.
Application Conditions
Input capacitor (CIN):
1.0 µF or more
Output capacitor (CL): 2.2 µF or more (tantalum capacitor)
Caution A general series regulator may oscillate, depending on the external components selected.
Check that no oscillation occurs with the application using the above capacitor.
