I'd like to be able to connect a few power good outputs from various LDO's and switchers together as they are open-drain. The TPS54225 says to connect the PG to VREG5 pin. VREG5 says it is approx 5V and I need to pass the PG chain to an FPGA running at 3.3V. Can the PG pin on the TPS54225 be connected to something besides VREG5? If so does VREG5 still need some resistor to PG or just the bypass cap?
