Notes

67.

When the LDO output voltage is set above 2.6 V, the minimum allowed input voltage need to be at least the output voltage plus 0.25 V for proper

regulation due to the dropout voltage generated through the internal LDO transistor.

68.

The PSRR of the regulators is measured with the perturbing signal at the input of the regulator. The power management IC is supplied separately

from the input of the regulator and does not contain the perturbed signal. During measurements, care must be taken not to operate in the dropout

region of the regulator under test. VIN2MIN refers to the minimum allowed input voltage for a particular output voltage.
