Note:
" Supply current 1 " is the supply current while the oscillator is continuously oscillating. In
actual operation the oscillator periodically operates. The current actually provided by an
external VIN source from VOUT pin.
" Supply current 2 " is the supply current while the oscillator stop oscillating. In actual
operation the oscillator periodically operates. The current actually provided by an external
VIN source from VOUT pin
