EGULATION 

 

See the Example Application Schematic for the regulator configuration. BT800 contains 5 regulators: 

 

USB linear regulator, to generate the 3.3 V for the USB interface and the input to the high-voltage 
linear regulator. 

 

High-voltage linear regulator, to generate the main 1.8V from the USB linear regulator or an 
external 3.3V. 

 

This regulator then feeds the 3 low-voltage regulators: 

 

Low-voltage VDD_DIG linear regulator, a programmable low-voltage regulator to supply a 0.90V 
to1.25V digital supply, VDD_DIG. 

 

Low-voltage VDD_ANA linear regulator, to supply the radio supply, VDD_RADIO. 

 

Low-voltage VDD_AUX linear regulator, to supply the auxiliary supply, VDD_AUX. 

 

USB Linear Regulator 

10.1

The integrated USB LDO linear regulator is available as a 3.30V supply rail and is intended to supply the 

USB interface and the high-voltage linear regulator. The input voltage range is between 4.25V and 

5.75V. The maximum current from this regulator is 150mA, of which 50mA is available for external use, for 

example EEPROM/LED. Externally decouple the output of this regulator using a low ESR MLC capacitor 

to the VREG_IN_HV pin. The regulator operates correctly with an output capacitor of 1µF to 4.7µF 

(±20%). 
This regulator is enabled by default. If the USB linear regulator is not required, leave its input 

(VREG_IN_USB) unconnected. 

 

High-voltage Linear Regulator 

10.2

The integrated high-voltage linear regulator is available to power the main 1.8 V supply rail. The input 

voltage range is between 2.3 V and 4.8 V. The maximum current from this regulator is 100 mA. Externally 

decouple the output of this regulator using a low ESR MLC capacitor of a minimum 1.5 µF to the 

VREG_OUT_HV pin. Take VREG_EN_RST# high to enable this regulator. If this regulator is not required then 

leave VREG_IN_HV unconnected or tied to VREG_OUT_HV.
