A source follower is an unusual choice for an LDO, since in theabsence of a separate bias supply input, it requires a complex charge pump to bias the gate. re there a significant number like that? The LTC3035 uses that style internally, but is optimized for VLDO, and only has 40 dB attentuation at 100 kHz, rather than 60. Could I inquire which parts you looked at that had similar PSRR? They would be useful to know about.
