Will the 3 terminal regulator breaks if used without load?

Latest Updated:12/01/2011


Do problems with the 3-terminal regulator, such as breakdown and temperature rise, occur if the regulator is used without load?


Generally, there is no problem even if the regulator is used without load. However, the possibility that oscillation occurs increases. Thoroughly evaluate the characteristics of the regulator in the application set.
Do not use variable output type regulators without load because the variable output types are prescribed to be used with the minimum output current (refer to Troubleshooting).
