Good evening, I am Purnendu from IITM. currently i am designing an RF board which works from DC-1GHz. Required power is 420mA@5V, 150mA@3.3V, 200mA@1.3V, 400mA@-2V, 420mA@-5V.
I have two question regarding this:
1. Should i use PMIC (as the components are sensitive, is the output of PMIC is clean enough to use it with RF systems.) or LDO.
2. Please suggest any regulator combination for this. (currently I have used 3 TPS7A4501 and 2 LM337 for this purpose but my adviser is pushing for lesser components).
