NOTES:
7. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
8. 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.
9. Dropout Voltage is the minimum V IN - V OUT differential voltage measured at the point where V OUT drops 1mV from V IN = nominal at T A = +25°C.
