28. REGULATOR FUNCTION
The V850ES/Jx3-E includes a regulator to reduce power consumption and noise.
This regulator supplies a stepped-down VDD power supply voltage to the oscillator block and internal logic circuits
except the A/D converter and output buffers). The regulator output voltage is set to 2.5 V (TYP.).
The outline of the regulator functions is shown below.
