Other Parts Discussed in Thread: LM4040, LM2903
I think that condition of LM4040 operate(output) is reach 60μA current, but LM4040DIM3-2.5 was not operate even if current flow 174μA by external resister.
Please let me know about condition of LM4040 operate and correction point of below schematic.
※Pattern 1・・・R119: 20kΩ, R120: 100kΩ ⇒ LM4040 is not output (174μA)
Pattern 2・・・R119: 10kΩ, R120: 39kΩ ⇒ LM4040 is normal output (427μA)
By the way, IC101 is LM2903.
Best regards,
Satoshi
