7.3.11 On-Chip Regulator

AFE has an internal regulator for generating the 1.8-V supplies (AVDD, DVDD) from the AVDD3 supply. In this mode, only one 3.3-V supply is sufficient for the device operation. Because the power is drawn from the 3.3-V supply for AVDD, DVDD, power consumption is higher. The REG_MODE pin controls the regulator. Connect this pin to IOVDD to enable regulator mode. In non-regulator mode, the REG_MODE pin should be connected to IOVSS. Figure 177 show the block diagram of the regulator. A decoupling capacitor of 100 nF minimum should be connected at the pins AVDD and DVDD. The decoupling capacitor on AVDD should be connected to AVSS, and the decoupling capacitor on DVDD should be connected to IOVSS.
