Notes:
4. All limits at operating temperature extremes are guaranteed by design, characterization and statistical quality control.
5. AC specifications guaranteed by design/characterization (not production tested).
6. For a case when VCC is higher than the typical 5V VCC. Voltage observed at VCC pin when the internal shunt regulator is sinking
current to keep voltage on VCC pin constant.
7. Test Conditions: VLDO_IN = 1.5V and VLDO_OUT = 1.2V
