CHAPTER 30 REGULATOR
30.1 Overview
The V850ES/JG3-H and V850ES/JH3-H include a regulator to reduce power consumption and noise.
This regulator supplies a stepped-down V
DD power supply voltage to the oscillator block and internal logic circuits
(except the A/D converter, D/A converter, and output buffers).
