Notes
1. The quiescent current is measured in standby mode when RL =
2. The rise and fall times are measured with a 50 pF load capacitor.

3. The reset delay time depends on the value of the reset delay capacitor:

4. The dropout voltage of a regulator is the voltage difference between VP and VO(REGn)
.
5. At current limit, VO(REGn) is held constant (see Fig.6).
6. The foldback current protection limits the dissipation power at short-circuit (see Fig.6).
7. The dropout voltage of regulator 2 is the voltage difference between VBUCAP and VO(REG2)
