NOTES:
9. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in V_OUT is
divided by the temperature range; in this case, -40°C to +125°C = +165°C.
10. Parts are 100% tested at +25°C and +85°C. The -40°C and +125°C temperature limits are established by characterization and
are not production tested.
