AS5403A/D/E − Operation

The AS5403 operates at 5V ±10%, using one internal

Low-Dropout (LDO) voltage regulator. For operation, the 5V

supply is connected to pin VDD. While VDD3 (LDO output) must

be buffered by 1μF capacitor, the VDD requires a 1μF capacitor.

All capacitors (low ESR ceramic) are supposed to be placed close

to the supply pins (see Figure 20).The VDD3 output is intended

for internal use only. It must not be loaded with an external load.

Connections for 5V Supply Voltages

Note(s) and/or Footnote(s):

1. The pin VDD3 must always be buffered by a capacitor. It must not be left

floating, as this may cause instable internal supply voltages which may lead

to larger output jitter of the measured angle.

The supply pin is over voltage protected up to 18V. In addition the device has

a reverse polarity protection.
