What happen if the 3 terminal regulator is continuously used with VIN?

Latest Updated:11/01/2006


What will happen if the 3-terminal regulator is continuously used with VIN lower than the recommended condition?


An output voltage almost equal to the input voltage is output.
Under such a condition, however, the electrical specifications and the operation of the protection circuits are not guaranteed. When a 3-terminal low dropout regulator is used, a high circuit current flows and the temperature rises if VIN is lower than the regulation start voltage.
