• CDC3S04: Can I use to 1.8V LDO output to power VDD_ANA?

  

  A. Choy

  Resolved

  Part Number: CDC3S04 Can I do the following? 1) Use the 1.8V LDO output to power VDD_ANA only? 2) Use the 1.8V LDO output to power both VDD_ANA and TCXO (as long as the 10mA current limit on V_LDO is no exceeded?) Thanks.
