12. APPLICATIONS INFORMATION
12-1. Stability
Linear regulators require input and output capacitors in
order to maintain the regulator's loop stability. If a 1.0F
capacitor is connected to 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.
A recommended value of the application is as follows.
C
In=1.0F, COut=1.0F
It is not possible to determine this indiscriminately.
Please confirm the stability in your design.
