ELECTRICAL CHARACTERISTICS: Continued (Notes)

NOTES:

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 4: Adjustable Version Only.
