8.2.2.6 LDO1 and LDO2

The LDOs in the TPS65023x are general-purpose LDOs which are stable using ceramics capacitors. The minimum output capacitor required is 2.2 μF. The LDOs output voltage can be changed to different voltages between 1 V and 3.3 V using the I2C interface. Therefore, they can also be used as general-purpose LDOs in applications powering processors different from DaVinci. The supply voltage for the LDOs needs to be connected to the VINLDO pin, giving the flexibility to connect the lowest voltage available in the system and provides the highest efficiency.
