LM3203, Step-Down DC-DC Converter
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.
The output voltage is set using a VCO
