NOTE:
6. Parameters with MIN and/or MAX limits are 100% tested at +25癈, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
Electrical Specifications Unless otherwise noted, all parameter limits are guaranteed over the recommended operating conditions
and the typical specifications are measured at the following conditions: T
A
= +25癈, VINDCD1 = 3.6V, VINDCD2 = 3.3V. For LDO1 and LDO2,
VINLDOx = VOLDOx + 0.5V to 5.5V with VINLDOx always no higher than VINDCD1, L
