PRODUCTION DATA
The internal LDO has a lower EN threshold than the output of the converter. When the EN pin voltage is above 1V (maximum) and below the precision enable threshold for the output voltage, the internal LDO regulates the VCC voltage at 3.3V typical. The internal power MOSFETs of the SW node remain off unless the voltage on EN pin goes above the precision enable threshold. The LMR436x0-Q1 also employs UVLO protection.
