This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect
reliability.
*The voltage input on IN, ST, and
PBRST
can be exceeded if the input current is less than 10 mA.
