CCS Technical Documentation
All regulators can be controlled individually with 2.78V logic directly or through control
register.
Use of the regulators can be seen in the power distribution diagram. VrefRF01 is used as
the reference voltages for the RX ADC`s reference in Mjoelner.
The regulators are connected to Mjoelner, either directly or through output loading net-
works. The individual regulator can be switched on/off through the serial data bus in
order to reduce the power consumption.
