手机设计中如何选择合适的LDO


Low-dropout LDO linear regulators are used to power many sections of a typical cellular handset.However, these baseband, RF, and audio sections have different requirements that influence which LDO is most appropriate. After scussion of the specific requirements, different LDOs are recommended. Also,some LDO design techniques are briefly discussed to demonstrate how an LDO may be optimized for aspecific level of performance.
