  • Stabilized power source circuit and IC incorporating the same
    Patent number: 5786970
    Abstract: A stabilized power source circuit is provided with an over current protecting circuit which obtains either a current value or a voltage value corresponding to an output current value of an output transistor as a detected value, compares the detected value with a predetermined constant value and lowers the output current when the detected value exceeds the predetermined constant value. A comparing value generating circuit receives an external signal, generates one of either a predetermined plurality of voltage values or a predetermined plurality of current values in response to the level of the received external signal and transmits the same to the over current protecting circuit as the predetermined constant value.
