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

The internal regulators described in Section 10.1 to Section 10.7 are not recommended for external circuitry other

than that shown in Section 12.

For information about power sequencing of external regulators to supply the CSR8635 QFN contact CSR.

10.10 Reset, RST#

CSR8635 QFN is reset from several sources:

■ RST# pin

■ Power-on reset

■ USB charger attach reset

■ Software configured watchdog timer
