Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2:
Unless otherwise specified: V

= 150 mA, T
= 25C, C1 = 0.1 μF, C2 = 10 μF. All characteristics except noise voltage and ripple rejection 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 sepa-
rately.
