9 Power Supply Recommendations

9.1 LDO1 Output Voltage Adjustment

The output voltage of LDO1 is set with a resistor divider at the feedback pin. The sum of the two resistors must not exceed 1 MΩ to minimize voltage changes due to leakage current into the feedback pin. The output voltage for LDO1 after start-up is the voltage set by the external resistor divider. It can be reprogrammed with the I2C interface to the three other values defined in the register VREGS1.
