(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.

Note 1: For best performance, an inductor with a saturation current rating higher than the maximum VOUT load requirement plus the inductor current ripple.
See the inductor current ripple calculations in inductor calculations sections.
Note 2: For best performance, a low ESR ceramic capacitor should be used – X7R or X5R types should be used. Y5V should be avoided.
Note 3: Min and max listed are to account for +/-20% variation of the typical value. Typical values of 10uF and 0.47uH are recommended.
