NOTE
For the chip-specific implementation details of this module's
instances see the chip configuration chapter.
The USB Voltage Regulator module is a LDO linear voltage regulator to provide 3.3V
power from an input power supply varying from 2.7 V to 5.5 V. It consists of one 3.3 V
power channel. When the input power supply is below 3.6 V, the regulator goes to pass-
through mode. The following figure shows the ideal relation between the regulator output
and input power supply.
