Troubleshooting of 3-terminal regulator
- The output voltage does not rise if a dual power supply circuit is created.
- The operation becomes unstable when the OUTPUT pin is pulled up with a resistor.
- With the variable output type, the output voltage exceeds the rated value if the output is opened.
- The output voltage drops when a load is connected.
- The output oscillates.
- The base metal is exposed at the roots of a pin.
