2.2.2 Q_LDO2 and Q_LDO3 output voltage selection*
To determine the output voltage levels of the three linear regulators, the selection pin
(SEL, pin 23) has to be connected according to the matrix given in the table below.
* for different output voltages please refer to the multi voltage supply TLE6361
