(1) All characteristics are measured with a 0.22 μF capacitor from input to ground and a 0.1 μF capacitor from output to ground. All
characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (t
w
≤ 10 ms, duty cycle ≤ 5%).
Output voltage changes due to changes in internal temperature must be taken into account separately.
