+0.6V voltage appears at V
OUT
pin.
*2 When the regulator is OFF, the V

pin is set to the high-impedance status.
*3 The mode selected depends on the line connection at the second stage of serial connection.
Voltage Regulator Circuit
The circuit receives a voltage from V
RI
pin, stabilizes it, and outputs at any voltage. The output is adjustable with
a ratio of R1 and R2 external divider resistors. Although the sum of divider resistors is desirable to be minimum
to prevent an interference due to external noise, 100 to 1 megohms are recommended as the current
consumption may be increased by the divider resistors.
Power Off Control
The SCI7654 has an automatic power-off function, and can turn on or off each function depending on the external
signals entered in POFF1 and POFF2 pins.
