Notes

65.

When the LDO Output voltage is set above 2.6 V, the minimum allowed input voltage needs 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.

66.

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.

All parameters are specified at PF0100Z TA = -40 °C to 85 °C, PF0100AZ TA = -40 °C to 105 °C, VIN = 3.6 V, VIN2 = 3.6 V,

VGEN4[3:0] = 1111, IGEN4 = 10 mA, typical external component values, unless otherwise noted. Typical values are characterized at

VIN = 3.6 V, VIN2 = 3.6 V, VGEN4[3:0] = 1111, IGEN4 = 10 mA, and 25 °C, unless otherwise noted.
