Notes

58.

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.

59.

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. VIN3MIN refers to the minimum allowed input voltage for a particular output

voltage.

Table 105. VGEN5 Electrical Characteristics

All parameters are specified at TA = -40 to 85 °C, VIN = 3.6 V, VIN3 = 3.6 V, VGEN5[3:0] = 1111, IGEN5 = 10 mA, typical external

component values, unless otherwise noted. Typical values are characterized at VIN = 3.6 V, VIN3 = 3.6 V, VGEN5[3:0] = 1111,

IGEN5 = 10 mA, and 25 °C, unless otherwise noted.
