Note 2. The convention for negative regulators in the algabraic value, thus –15V is less than –10V.
Note 3. Dropout Voltage is defined as that input–output voltage differential which causes the output
voltage to decrease by 5% of its initial value.
Note 4. All characteristics except noise voltage and ripple rejection ratio are measured using pulse
techniques (tW ≤ 10ms, duty cycle ≤ 5%). Output voltage changes due to changes in internal
temperature must be taken into account separately.
