DESCRIPTION

(Continued) ence, digitally trimmed, assures the selected output voltage to within +/-1% over temperature and battery voltage variations. Thanks to the remote sensing inputs and to the window comparator system, embedded in the error summing structure, the device provides excellent load transient performance.
