PRODUCTION CONSIDERATIONS
Notes
These surface-mount components are designed to comply with standard reflow
production methods. The recommended reflow profile is shown below and
should not be exceeded, as permanent damage to the part may result.
1. Current consumption with no active loads.
2. For 3V supply, (0.15 x 3.0) = 0.45V max.
3. For 3V supply, (0.8 x 3.0) = 2.4V min.
