Notes:

5) Guaranteed by characterization. Not tested in production.

6) When VIN is between 4.3V and 4.5V, ELVDD line regulation increases since VIN is close to ELVDD’s VOUT.

7) To improve ELVSS line regulation in heavy load when VIN < 3.5V, use an external Schottky diode as a rectifier between ELVSS and SW2.
