: Care must be taken when adjusting the VRANGE[ ] selection at address 23h bit-6 to avoid undesired output voltage selections. The
VRANGE bit allows selection of the two output voltage ranges available for REG1, REG2 and REG3 (VRANGE = 0 – VOUT range 0.8V
to 2.2V, VRANGE = 1 – VOUT range 1.3V to 4.4V). It is recommended that the user first establishes if the new VOUT voltage is within the
current selected voltage range (selected by VRANGE) prior to changing the value of the VRANGE bit.
: Refer to the Output Voltage Programming section for more information.
