Note 1: Output temperature coefficient is defined as the worst case voltage change divided by the total temperature range
Note 2: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its
nominal value measured at 1V differential at very low values of programmed output voltage, the minimum input supply
voltage of 2V (2.3V over temperature) must be taken into account.
Note 3: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is
applied. Excluding load or line regulation effect.
Note 4: Adjustable Version Only.
