Power Supply
6
The circuit can be supplied from a 3 V voltage regulator or battery cell by connecting VCCIN and
VCCINOUT. It is also possible to use a 5 V power supply connected to VCCIN; in this case VCCINOUT
should not be connected to VCCIN.
An on-chip low drop-out voltage regulator supplies the RF and analog modules (except the strobe
oscillator and the low voltage detector, which are directly supplied from VCCINOUT). This voltage
regulator is supplied from pin VCCINOUT and its output is connected to VCC2OUT. An external
capacitor must be inserted between VCC2OUT and GND for stabilization and decoupling. The analog and
RF modules must be supplied by VCC2 by externally wiring VCC2OUT to VCC2IN, VCC2RF and
VCC2VCO.
A second voltage regulator supplies the digital part. This regulator is powered from pin VCCDIG and its
output is connected to VCCDIG2. An external capacitor must be inserted between VCCDIG2 and
