Hi, I am trying to implement a GPS tracker. I have microcontroller, GPS and GSM modules and several other things. But they require different supply voltages. ( 3.3,3.8 and 5 V ). I will use a single battery but I need to produce multiple voltage levels out of it. Could you recommend me an IC that could make the conversion ?

Thank you in advance for your answers.
 

What is the battery voltage and rating? How much current approximately these devices would draw? It is not just about deriving voltages.
you may start with listing out each required voltage levels, and power consumed by each modules etc. and then go for deciding the right component
