Externally decouple the output of this regulator using a low ESR MLC capacitor of a minimum 2.2µF to the 3V3_USB
pin.
The output voltage is switched on when VCHG gets above 3.0V.
10.5 Low-voltage VDD_DIG Linear Regulator
The integrated low-voltage VDD_DIG linear regulator powers the digital circuits on CSR8615 QFN. Externally
decouple the output of this regulator using a low ESR MLC capacitor of 470nF.

10.9 External Regulators and Power Sequencing
CSR recommends that the integrated regulators supply the CSR8615 QFN and it is configured based on the
information in this data sheet.
If any of the supply rails for the CSR8615 QFN are supplied from an external regulator, then it should match or be
better than the internal regulator available on CSR8615 QFN. For more information see regulator characteristics in
Section 13.
