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 @ TA = +25°C after temperature cycling over a specified range, ΔTA. 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 ΔTA = +165°C, the device under test is cycled from +25°C to
-40°C to +125°C to +25°C.
