Note 1: Functional test only.
Note 2: Dropout voltage is defined as the input to output differential at which the output
drops 100mV below its nominal values 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: Comparator thresholds are expressed in terms of a voltage differential at the
Feedback terminal below the nominal reference voltage measured at Vin = 6V. To
express these thresholds in terms of output voltage change, multiply by the error
amplifer Gain=Vout/Vin=(R1 + R2)R2. For example, at a programmed output voltage of
5V, the error output is guaranteed to go low when the output drops by 95mV X
5V/1.235V = 384mV. Thresholds remain constant as a percent of Vout as Vout is varied,
with the dropout warning occuring at typically 5% below nominal, 7.5% guaranteed.
