Found in American documentation from the 90s, this circuit uses TTL technology and is therefore compatible with microcontroller drives. The circuit must be powered by a 5V power source.
This circuit is from the datasheet of STMicroelectronics, being indicated for the voltage...
In this circuit the CA3140, an operational amplifier, is used as a comparator with the zener diode...
We found this voltage regulator for 5 V with current up to 10 A in an old manual of integrated circuits....
