2.1.5 Core LDO (CLDO)

The device has an internal core LDO, and its output is connected to pin 10 (CLDO_O) to add an external decoupling capacitor. The output of the core LDO regulator is 1.2V, and it is named “VDD_1P2V”. Do not use this VDD_1P2V to power any other external circuitry. C10, referred to in Figure 2-4, must be placed closer to the pin followed by C11 in the Printed Circuit Board (PCB) layout.
