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.

请查询相应 PSRAM 芯片以及 {IDF_TARGET_NAME} 的技术规格书获取准确的工作电压。
PSRAM 默认由片上 LDO2 供电。可设置 :ref:`CONFIG_ESP_VDD_PSRAM_LDO_ID` 来切换相应的 LDO ID，将该值设为 -1 表示使用外部电源，即不使用片上 LDO。默认情况下，连接到 LDO 的 PSRAM 会基于所使用的乐鑫模组设置正确电压。如果未使用乐鑫模组，仍可设置 :ref:`CONFIG_ESP_VDD_PSRAM_LDO_VOLTAGE_MV` 来选择 LDO 输出电压。使用外部电源时，该选项不存在。
