Features
(1) Use three such LDOs to power up DVDDA, DVDDB, DVDDC (It can either be 1.8 V or 3.3 V)
(2) Rx = 0.499 Mâ¦, Ry = 1 M⦠for Vout = 1.8 V
(3) Rx = 1.8 Mâ¦, Ry = 1 M⦠for Vout = 3.3 V
(4) For proper sequencing of output, enable of the LDOs are fed either from 1.2-V output from 1.2-V output from
TPS62232 if DVDDX is 1.8 V or from 1.8-V output from TPS62231 if DVDDX is 3.3 V.
