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 25mA
operation are inherently limited by the ON-resistance of internal device. Since this resistance is in the range of 1 Ω ,
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 25mA
