Note 1: The output voltage at light loads has a DC regulation level higher than the error comparator threshold by half the ripple volt-
age.
Note 2: The dropout voltage is defined as V LDOIN - V OUT_ when V LDOIN = V OUT_(NOM) . Specification only applies when V OUT_ ≥
2.5V.
Note 3: OUT1, OUT2 DC set point, FB3 set point at the DC trip threshold of buck regulator.
Note 4: Specifications to -40 ° C are guaranteed by design, not production tested.
