(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute–maximum–rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.
(3) ESD testing is performed according to the respective JESD22 JEDEC standard.

Note 1: For best performance, an inductor with a saturation current rating higher than the maximum VBAT load requirement plus the inductor current ripple.
Note 2: For best performance, a low ESR ceramic capacitor should be used.
Note 3: For best performance, a low ESR ceramic capacitor should be used. If CIN is not a low ESR ceramic capacitor, a 0.1uF ceramic capacitor should be
added in parallel to CIN.
