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
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 2.7V.
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 2.7V.
