10.5 Low-voltage VDD_DIG Linear Regulator

The integrated low-voltage VDD_DIG linear regulator powers the digital circuits on CSR8635 QFN. Externally decouple

the output of this regulator using a low ESR MLC capacitor of 470nF.

10.6 Low-voltage VDD_AUX Linear Regulator

The integrated low-voltage VDD_AUX linear regulator is optionally available to provide a 1.35V auxiliary supply rail

when the 1.35V switch-mode regulator is not used. When using the integrated low-voltage VDD_AUX linear regulator,

externally decouple the output of this regulator using a low ESR MLC capacitor of a minimum 470nF to the VDD_AUX

pin.

10.7 Low-voltage VDD_ANA Linear Regulator
