Note : The spec. of “load current” above is sum of the load current of two internal voltage regulator.
Example circuit for Regulator
* Same circuit need to be mounted both for two regulator pins.
(No.42 and No.90)
* The capacitor C1 must be greater than 50F and low Secure
50F 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.
