7.2.2 Detailed Design Procedure

Select a 3.3V output, fixed or adjustable device to generate the 3.3V rail. The fixed-version LDO has internal feedback divider resistors, and thus has lower quiescent current. The adjustable-version LDO requires external feedback divider resistors, and is described in the Selecting Feedback Divider Resistors section.
