What happens to 3-terminal regulator if output current exceeds?

Latest Updated:12/01/2011


Is there any problem with the 3-terminal regulator if the recommended output current shown in the data sheet is exceeded?


It is considered that the 3-terminal regulator does not break down even if the maximum value of the output current (1 A for the uPC2900 Series) is exceeded.
An output current is not specified for the 3-terminal regulator. The 3-terminal regulator has an internal overcurrent restriction circuit to restrict the overcurrent under overload condition. If the output current exceeds the recommended condition, however, the characteristic values are not guaranteed. We recommend choosing another IC.
