Product data sheet
7.4 Power supply input options
The ISP1105/1106 range has two power supply input options.
Internal regulator — V
used to supply the internal circuitry with 3.3 V (nominal). The V
output reference.
Regulator bypass — V
regulator is bypassed and the internal circuitry is supplied directly from the V
supply. The voltage range is 3.0 V to 3.6 V to comply with the USB specification.
The supply voltage range for each input option is specified in
Table 10.
