Some PSRAM chips are 1.8 V devices and some are 3.3 V. Consult the datasheet for your PSRAM chip and {IDF_TARGET_NAME} device to find out the working voltages.
By default, the PSRAM is powered up by the on-chip LDO2. You can use :ref:`CONFIG_ESP_VDD_PSRAM_LDO_ID` to switch the LDO ID accordingly. Set this value to -1 to use an external power supply, which means the on-chip LDO will not be used. By default, the PSRAM connected to LDO is set to the correct voltage based on the Espressif module used. You can still use :ref:`CONFIG_ESP_VDD_PSRAM_LDO_VOLTAGE_MV` to select the LDO output voltage if you are not using an Espressif module. When using an external power supply, this option does not exist.
By default, the PSRAM is powered up by the on-chip LDO2. You can use :ref:`CONFIG_ESP_LDO_CHAN_PSRAM_DOMAIN` to switch the LDO channel accordingly. Set this value to -1 to use an external power supply, which means the on-chip LDO will not be used.
