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
