The CSI in {IDF_TARGET_NAME} requires stable 2.5V power supply. Please refer to the schematic diagram to ensure that the power supply pins are connected to 2.5V power before using the MIPI CSI driver.
.. only:: SOC_GP_LDO_SUPPORTED
In {IDF_TARGET_NAME}, the CSI can be powered by the internal adjustable LDO. Please connect the LDO channel output pin to the CSI power supply pin. Then, before initializing the CSI driver, use the API provided in :doc:`/api-reference/peripherals/ldo_regulator` to configure the LDO to output 2.5 V voltage.
