The following recommendations on components selection focus on the design of an efficient push-pull converter with high current drive capability. Contrary to popular belief, the output voltage of the unregulated converter output drops significantly over a wide range in load current. The characteristic curve in Figure 8-2 and Figure 8-3 for example, shows that the difference between V_OUT at minimum load and V_OUT at maximum load exceeds a transceiver supply range. Therefore, to provide a stable, load independent supply while maintaining maximum possible efficiency the implementation of a low dropout regulator (LDO) is strongly advised.
