Powering VDD3P3_RTC with 3.3V 30mA always on LDO
Posted: Sun Mar 12, 2023 6:49 am
Is it possible to power RTC from a 3.3V 30mA always on output from LDO to keep RTC running while chip is off? I know the pin supplies VDD_SPI and i'm using that to power flash and psram running at 25mA and 40mA, respectively. Can I power flash and psram from external LDO and have VDD3P3_RTC dedicated to RTC?
