Note:

Simulation data
This regulator is designed to supply the device internal circuits (PLLs, MIPI PHY, USB PHYs, oscillators, etc.). To supply external components, only DC current is permissible (for example, a resistive divider).
Input current when charging the external output capacitor C_OUT.
A X5R or X7R ceramic capacitor connected between VDDIN33 and the device’s closest GND pin is a minimum requirement to reduce the inrush current and maximize the regulator’s performances.
To ensure stability, an external X5R or X7R ceramic output capacitor, C_OUT, must be connected between the VDDOUT25 and the device’s closest GND pin.
