Notes:
4. No load supply current is measured when the oscillator is off.
5. The short circuit protection is designed to protect against pre-existing short circuit conditions, i.e. assembly shorts
that exist prior to device power-up. The short circuit current limit is 25mAAverage. Short circuit currents in normal
operation are inherently limited by the ON-resistance of internal device. Since this resistance is in the range of 1Ω,
in some cases thermal shutdown may occur. However, immediately following the first thermal shutdown event, the
short circuit condition will be treated as pre-existing, and the load current will reduce to 25mAAverage.
