NOTE:
6. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
7. Not tested in production. Characterized using evaluation board. Refer to Figures 12 through 14 load regulation diagrams. +105°C TA represents near
worst case operating point.
