Note:
  1. Simulation data
  2. This regulator is designed to supply the device internal circuits (PLLs, MIPI PHY, LVDS PHY, oscillators, etc.). To supply external components, only DC current is permissible (for example, a resistive divider) up to ILOAD_EXT_MAX.
  3. Input current when charging the external output capacitor COUT.
  4. An 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 performances.
  5. To ensure stability, an external X5R or X7R ceramic output capacitor, COUT, must be connected between the VDDOUT25 and the device’s closest GND pin.
