C1
* Same circuit need to be mounted both for two regulator pins.
(No.58 and No.124)
* The capacitor C1 must be greater than 50F and low Secure
50F or more for low ESR and the capacity value in the range
of the operating temperature so that there is a possibility of the
oscillation when the capacity value changes by the temperature
change etc.
(The recommended value is 100F.)
