ok cool. The one I’ve seen done wrong was being fed V_USB, but had the 3.3V output tied to the main 3.3V net, in parallel with another 3.3V LDO. Worked fine as long as there wasn’t a decent load transient, like if you took control of the GPS and enabled forced-standby on a GPIO, then released it from standby which caused an instantaneous ~100mA load. Confirmed fix was to cut the connection between the the UART’s 3V3 net and the system’s 3V3 net
