100F
C1
* Same circuit needs to be mounted both for two regulator pins.
(No.44 and No.87)
* C1 is for capacitor to stop oscillation.
There is a possibility of oscillation due to temperature change and etc., so C1
must be greater than 50F and low ESR at the operational temperature.
(The recommended value is 100F)

C1
* Build a circuit shown at left for the regulator pin No. 90.
* C1 is for capacitor to stop oscillation.
There is a possibility of oscillation due to temperature change and etc., so C1
must be greater than 50F and low ESR at the operational temperature.
(The recommended value is 100F)
