Fault phenomenon: low startup current
Maintenance methods:
1. Check the model of the two regulators to prevent wrong loading of
materials.
2. Check the voltage at each point:
Checkpoint
Voltage V
Name
B7
+9
Internal 9V voltage
B8
+5
Internal 5V voltage
In some cases, the low startup current is probably due to the
wrong material loading of the two regulators.
