ZHCSKN9B December 2019 – December 2022 LMR36506
PRODUCTION DATA
The internal LDO has a lower EN threshold than the output of the converter. When the EN pin voltage is above 1.1 V (maximum) and below the precision enable threshold for the output voltage, 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 of the SW node remain off unless the voltage on EN pin goes above its precision enable threshold. The LMR36506 also employs UVLO protection. If the VCC voltage is below its UVLO level, the output of the converter is turned off.
