CHAPTER 32 REGULATOR
32.2 Operation
The regulators of the V850ES/JH3-E and V850ES/JJ3-E always operate in any mode (normal operation mode, HALT
mode, IDLE1 mode, IDLE2 mode, STOP mode, subclock operation mode, sub IDLE mode, or during reset).
Be sure to connect a capacitor (4.7 μF (recommend value)) to the REGC pin^Note to stabilize the regulator output.
A diagram of the regulator pin connection method is shown below.
Note There are two REGC pins.

Caution The V850ES/JH3-E and V850ES/JJ3-E have two regulators. Therefore, connect each of the two
REGC pins to a capacitor.
