Other Parts Discussed in Thread: TPS7A92
Hi team,
Due to stringent requirements for noise performance, one of our customers needs to use 2 LDOs to power digital voltage VD11 and analog voltage VA11, rather than use common 1.1VDC regulator for VA11 and VD11. If VD11 and VA11 are not from the same IC, So how big can the difference between VD11 and VAD11 be allowed during power up/power down procedure? Or, can't use 2 LDOs to power VD11 and VA11 respectively?
Best Regards,
Amy Luo
