R1

Resistor for ILM voltage adjustment

ILM output voltage

R1:without = 12.0V

:270k

Ω = 10.0V

A resistor with resistance accuracy as

low as less than

±1% must be used.

R2, R3

Resistor for AUDIO voltage setting

R2/R3:30k

Ω/5.6kΩ = 8.0V

:27k

Ω/4.7kΩ = 8.5V

:24k

Ω/3.9kΩ = 9.0V

A resistor with resistance accuracy as

low as less than

±1% must be used.

D1, D2, D3, D4

Diode for internal device breakdown protection

Recommendation:

SBD1003M3(30V/1.0A)

* : In order to stabilize the regulator outputs, it is recommended that the electrolytic capacitor and ceramic capacitor be connected in parallel.

Moreover, the above-mentioned value doesn't guarantee the operation stability in use and the overcurrent protection operation by IOmax or more of the

regulator. Therefore, there is a possibility of oscillating by use conditions.
