AS5047U − Detailed Description

Power Management

The AS5047U can be either powered from a 5.0V supply using

the on-chip low-dropout regulator or from a 3.3V voltage

supply. The LDO regulator is not intended to power any other

loads, and it needs a 1

μF capacitor to ground located close to

chip for decoupling as shown in Figure 11.

In 3.3.V operation, VDD and VREG shall connected together. In

this configuration, normal noise performance (ONL) is available

at reduced maximum temperature (125°C) by clearing

NOISESET to 0. When NOISESET is set to 1, the full temperature

range is available with reduced noise performance (ONH).
