Notes

53.

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.

Table 102. VGEN2 Electrical Characteristics

All parameters are specified at TA = -40 to 85 °C, VIN = 3.6 V, VIN1 = 3.0 V, VGEN2[3:0] = 1111, IGEN2 = 10 mA, typical external

component values, unless otherwise noted. Typical values are characterized at VIN = 3.6V, VIN1 = 3.0 V, VGEN2[3:0] = 1111,

IGEN2 = 10mA and 25°C, unless otherwise noted.
