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 V_OUT is divided by the
temperature range; in this case, -40°C to +125°C = +165°C.
10. Dropout Voltage is the minimum V_IN - V_OUT differential voltage measured at the point where V_OUT drops 1mV from V_IN = 5.0V at T_A = +25°C.
11. Thermal Hysteresis is the change of V_OUT measured @ T_A = +25°C after temperature cycling over a specified range, ΔT_A. V_OUT is read initially at
T_A = +25°C for the device under test. The device is temperature cycled and a second V_OUT measurement is taken at +25°C. The difference between
the initial V_OUT reading and the second V_OUT reading is then expressed in ppm. For ΔT_A = +165°C, the device under test is cycled from +25°C to
-40°C to +125°C to +25°C.
