NOTE 3:To get the real quiescent current of the device, the quiescent current of the reference voltage
generator (140uA typ.) has to be added together once for all regulators.
NOTE 4:VOUT does not drop below 2.7V for more than 1us.
NOTE 5:VOUT does not drop below 2.5V for more than 1us or below 2.7V for more than 50us.
