Resistor for ILM voltage adjustment
Resistor for AUDIO voltage setting
Diode for internal device breakdown protection
ILM output voltage
R1:without = 12.0V
:270kΩ = 10.0V
:100kΩ = 8.0V
AUDIO output voltage
R2/R3:30kΩ/5.6kΩ = 8.0V
:27kΩ/4.7kΩ = 8.5V
:24kΩ/3.9kΩ = 9.0V
A resistor with resistance accuracy as
low as less than ±1% must be used.
A resistor with resistance accuracy as
low as less than ±1% must be used.
* : In order to stabilize the regulator outputs, it is recommended that the electrolytic capacitor and ceramic capacitor be connected in parallel.
Furthermore, the values listed above do not guarantee stabilization during the overcurrent protection operations of the regulator, so oscillation may occur
during an overcurrent protection operation.
