2.9 Power Supply Circuit

In the SH7670 CPU board, 5V-power supply is input to the board to generate 3.3V and 1.2V by a regulator.

The regulator used is an output voltage variable type so that any voltage value can be generated by changing the

resistance.

Figure 2.9.1 shows the block diagram of SH7670 CPU board power supply circuit.
