PRODUCTION DATA
The internal LDO has a lower enable threshold than the output of the converter. When the EN pin voltage is above 1.1 V (maximum) and below the precision enable threshold, the internal LDO regulates the VCC voltage at 3.3 V typical. The precision enable circuitry is ON after VCC is above its UVLO. The internal power MOSFETs remain off unless the voltage on EN goes above its precision enable threshold. The converter also employs UVLO protection. If the VCC voltage is below its UVLO level, the output of the converter is turned off.
