ESP32-P4 LDO
The ESP32-P4 has 4 Low-Dropout linear regulators that can be used to power on- and off-chip peripherals. This component allows those regulators to be configured and enabled.
# Example configuration entry
esp_ldo:
- channel: 3
voltage: 2.5V
- channel: 4 // example for sd activation on Guition JC-ESP32-P4-M3 dev board
voltage: 3.3V // GPIO45 on these boards can then do PWM on that power supply line on runtime (ledc)Configuration variables
- channel (Required, int): The channel number of the LDO regulator to configure. Only channels 3 and 4 are supported (1 and 2 are used internally by the chip.)
- voltage (Required, voltage): The desired output voltage - must be in the range 0.5V to 3.3V. Default is 2.7V. 3.3V in case LDO is used for SD-card slot power.
- adjustable (Optional, bool): If true, the output voltage can be adjusted at run-time. Defaults to false.
esp_ldo.voltage.adjust Action
If the LDO is adjustable, the voltage can be updated at runtime:
on_...:
then:
- esp_ldo.voltage.adjust:
id: ldo_id
voltage: !lambda return 2.5;Configuration variables
- id (Required, ID) The ID of the LDO to adjust.
- voltage (Required, voltage): The desired output voltage - must be in the range 0.5V to 3.3V. Defaults to 2.7V
