Digital LDO Voltage Tables A and B
A 5-bit linear DAC controls the output voltage of each LDO. The DAC and error-amp gain are scaled so that the LSB
size at the output is 50mV. Output voltage can be set by writing the proper code to the desired LDO register. See Table
A for the bitcodes and their corresponding voltages for LDO CORE, and Table B for bitcodes and their corresponding
voltages for LDOs PAD, MOT and CAM.
