Notes
1. Minimum operating voltage, only if VP has exceeded 4.5 V.
2. The quiescent current is measured in the standby mode. So, the enable inputs of regulator 1, 2 and 3 are LOW
(Ven < 1 V).
3. The drop-out voltage of regulators 1, 2 and 3 is measured between VP and VREGn.
4. At current limit, IREGmn is held constant (see Fig.4 for behaviour of IREGmn).
5. The foldback current protection limits the dissipated power at short-circuit (see Fig.4).
6. Perform the load regulation test with sine wave load of 10 kHz on the regulator output under test. Measure the RMS
ripple voltage on each of the remaining regulator outputs, using a 80 kHz low-pass filter.
