NOTE 1: The reverse battery current is measured from the Typical Operating Circuit's input terminal to GND
when the battery is connected backward. A reverse current of 220mA will not exceed package dissipation limits
but, if left for an extended time (more than 10 minutes), may degrade performance.
NOTE 2: Specifications to -40
NOTE 3: Inductor Peak Current where .
