ABSOLUTE MAXIMUM RATINGS

Note: 1. This parameter applies when the start up current source is off. This is the case when the VDD voltage has reached VDDon and

remains above VDDoff.

2. This parameter applies when the start up current source is on. This is the case when the VDD voltage has not yet reached VDDon

or has fallen below VDDoff.

THERMAL DATA

Note: 1. When mounted on a standard single-sided FR4 board with 200 mm² of Cu (at least 35

µm thick) connected to all DRAIN pins.
