What happens if VIN gets close to VOUT on a 3 terminal regulator continuously?

Latest Updated:11/01/2006

Question:

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

Answer:

If the output voltage almost equals the input voltage, 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.
