(5) Thermal hysteresis is defined as the changes in +25°C output voltage before and after the cycling of the device from 0°C to 70°C.
(6) Dropout voltage is defined as the minimum input to output differential voltage at which the output voltage drops by 0.5% below the value
measured with V
IN
= 3.0V for the LM4140-1.024 and LM4140-1.250, V
IN
= 5.0V for all other voltage options.
(7) The output noise is based on 1.024V option. Output noise is linearly proportional to V
