I have a question from our customer about the internal LDO for VCO of ADF4372.
Q1. About bit7 of REG002F, "SWITCH_LDO_3P3_5V" usage.
Can he select the voltage, 3.3v or 5v, of VCC_REG_OUT outputs using this register?
If not, could you please explain the purpose of this register and how to use this?
Q2. If Q1 is yes, what voltage for VCC_LDO should be higher than VCC_REG_OUT? (What voltage is needed for the headroom?)
Q3. If REG002F does not affect the output voltage of VCC_REG_OUT, what voltage will be output from VCC_REG_OUT, when 5v be input to VCC_LDO?
