ILM output voltage
R1:without = 12.0V
:270kΩ = 10.0V
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.
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.
