Additional preview pages of the LM3203 datasheet.

The LM3203 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell.

However, they may be used in many other applications.

It steps down an input voltage of 2.7V to 5.5V to an adjustable output voltage of 0.8V to 3.6V.
