PRODUCTION DATA
The internal LDO for the VCC bias supply has a lower enable threshold than the regulator itself. When VEN is above 1.1 V (maximum) and below the precision enable threshold of 1.263 V (typical), the internal LDO is on and regulating. The precision enable circuitry is turned on after the internal VCC is above its UVLO threshold. The switching action and voltage regulation are not enabled until VEN rises above the precision enable threshold.
