9.4 Voltage Regulators (AVREG, DVREG)
The main features of the Voltage Regulator blocks are:
? Bandgap stabilized 1.8V supply for analog and digital domain
? Low dropout (LDO) voltage regulator
? Configurable for usage of external voltage regulator
9.4.1 Overview
The internal voltage regulators supply a stabilized voltage to the Atmel AT86RF232.
The AVREG provides the regulated 1.8V supply voltage for the analog section and the
DVREG supplies the 1.8V supply voltage for the digital section.
A simplified schematic of the internal voltage regulator is shown in Figure 9-7 .

The voltage regulators require bypass capacitors for stable operation. The value of the
bypass capacitors determine the settling time of the voltage regulators. The bypass
capacitors shall be placed as close as possible to the pins and shall be connected to
ground with the shortest possible traces.
9.4.2 Configuration
The voltage regulators can be configured by the register 0x10 (VREG_CTRL).
It is recommended to use the internal regulators, but it is also possible to supply the low
voltage domains by an external voltage supply. For this configuration, the internal
regulators need to be switched off by setting the register bits to the values
AVREG_EXT = 1 and DVREG_EXT = 1. A regulated external supply voltage of 1.8V
needs to be connected to the pins 13, 14 (DVDD) and pin 29 (AVDD). When turning on
the external supply, ensure a sufficiently long stabilization time before interacting with
the AT86RF232.
9.4.3 Data Interpretation
The status bits AVDD_OK = 1 and DVDD_OK = 1 of register 0x10 (VREG_CTRL)
indicate an enabled and stable internal supply voltage. Reading value zero indicates a
disabled or internal supply voltage not settled to the final value.
