NOTES:

8. Compliance to datasheet limits is assured by one or more methods: production test, characterization, and/or design.

9. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the

temperature range; in this case, -40°C to +125°C = +165°C.

10. Dropout Voltage is the minimum VIN - VOUT differential voltage measured at the point where VOUT drops 1mV from VIN = nominal at TA = +25°C.

11. Thermal Hysteresis is the change of VOUT measured at TA = +25°C after temperature cycling over a specified range, TA. VOUT is read initially at

TA = +25°C for the device under test. The device is temperature cycled and a second VOUT measurement is taken at +25°C. The difference between

the initial VOUT reading and the second VOUT reading is then expressed in ppm. For TA = +165°C, the device under test is cycled from +25°C to

-40°C to +125°C to +25°C.
