Analog Devices LTC7804

The LTC7804 operates from a wide 4.5V to 40V input supply range. When biased from the boost converter output , the LTC7804 can operate from an input supply as low as 1V after startup. The very low no-load quiescent current extends operating runtime in battery powered systems.
