input voltage. This feature translates to maximum effi- ciency at all battery voltages. ♦
±1% Initial Accuracy
The MAX6520 operates from a supply voltage as low as 2.4V, and initial accuracy is ±1% for the SOT23 pack- age.
Output voltage temperature coefficient is typi- cally only 25ppm/°C, and is guaranteed to be less than 50ppm/°C in the SOT23 package. ______________Ordering Information ________________________Applications PIN- TOP
