30.2 Operation
The regulators of the V850ES/JG3-H and V850ES/JH3-H 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
μ F (recommended 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/JG3-H and V850ES/JH3-H have two regulators. Therefore, connect each of the
two REGC pins to a capacitor.
