Analog LDO Voltage Tables C and D

The bit code controls the output voltage of each LDO. 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 C for the bitcodes and their corresponding voltages

for LDO ANA, and Table D for the bitcodes and their corresponding voltages for LDOs TCXO, TX, RX and PLL.
