ANT+B (VCC 500mA)
AMP+B (VCC 100mA)
VCC-1V unstabilized outputs that can provide 100 or 500mA
The on/off state of these outputs can be controlled with serial
data.
Used with the ANT+B and AMP+B systems.

Pin 6: Power supply.
*: This pin must be at the same potential as the emitter of the
external transistor.
11
CONT
Pin 11: Bias for the external transistor.
The maximum sink current is 20mA.
12
CN1
Pin 12: Ripple rejection for each of the power supply systems.
To increase the rejection capacity, insert a 1
μF capacitor
between this pin and pin 27.
This pin controls the COM10V output voltage.
The voltage is set to 10V internally.
27
COM10V
Pin 27: The 10V power supply used for CD power, tuner VT,
cassette loading, LCD, and ILL illumination.
Used as the power supply for internal 8V and 5V
(except VDD5V) systems.
The output voltage can be controlled with the CN1 pin.
The ripple rejection can be improved at the CN1 pin.

When +B is applied to the VCC 6 pin, 5V is output.
Used as the power supply for systems, such as the
microcontroller, that require memory backup.
IQ = 600 to 780μA
