12-1. Stability
Linear regulators require input and output capacitors in
order to maintain the regulator's loop stability. If 2.2µF
capacitors are connected to the input side and the output
side, the IC provides stable operation. However, it is
recommended to use as large a value capacitor as is
practical. The output noise and the ripple noise decrease
as the value of the capacitor increases.
Please confirm the stability in your design.
A recommended value of the application is as follows.
It is not possible to determine this indiscriminately.
