1 For
input and output current specifications, negative current is defined as coming out of the node or pin (sourcing); positive current is defined as
going into the node or pin (sinking).
2 Ensured by design and characterization, not production tested.
3 Minimum V
IN = 5 V is only required at startup. After startup is completed, the IC is able to function down to V IN = 4 V.
