ADAU1701
Rev. B | Page 19 of 52
VOLTAGE REGULATOR
Two specifications must be considered when choosing a regulator
transistor: The transistor’s current amplification factor (hFE or
beta) should be at least 100, and the transistor’s collector must
be able to dissipate the heat generated when regulating from
3.3 V to 1.8 V. The maximum digital current drawn from the
ADAU1701 is 60 mA. The equation to determine the minimum
power dissipation of the transistor is as follows:
The digital voltage of the ADAU1701 must be set to 1.8 V. The
chip includes an on-board voltage regulator that allows the
device to be used in systems without an available 1.8 V supply
but with an available 3.3 V supply. The only external components
needed in such instances are a PNP transistor, a resistor, and a
few bypass capacitors. Only one pin, VDRIVE, is necessary to
support the regulator.
(3.3 V 1.8 V) × 60 mA = 90 mW
There are many transistors, such as the FZT953 from Zetex
Semiconductors, with these specifications available in small
SOT-23 or SOT-223 packages.
The recommended design for the voltage regulator is shown
in Figure 16. The 10 μF and 100 nF capacitors shown in this
configuration are recommended for bypassing, but are not
necessary for operation. Each DVDD pin should have its own
100 nF bypass capacitor, but only one bulk capacitor (10 μF to
47 μF) is needed for both DVDD pins. With this configuration,
3.3 V is the main system voltage; 1.8 V is generated at the
transistor’s collector, which is connected to the DVDD pins.
VDRIVE is connected to the base of the PNP transistor. If the
regulator is not used in the design, VDRIVE can be tied to ground.
