The device can also be used in medical devices due to its fast turn-on time and low output temperature coefficient.

Working Principle

The L78L08ACUTR voltage regulator is a three-terminal regulator that operates in a linear manner. The output voltage of the regulator is constant and is determined by the voltage applied to its reference terminals, which is usually 5V or 8V.The regulator is connected to its input source, either a battery or power supply, by two resistors. The input resistors increase the input voltage until the voltage at the reference terminals reaches the desired output voltage. When the correct voltage is reached, the regulator will start to adjust its output voltage such that it remains constant.The L78L08ACUTR regulator has an internal current limit which prevents the output voltage from going too high and damaging the circuit. This current limit is set to a value that takes into account the input voltage and output voltage, so the regulator will automatically adjust the output voltage depending on the input voltage and output voltage.

Conclusion

The L78L08ACUTR is a widely used linear voltage regulator and is suitable for a variety of applications due to its low power consumption, wide input voltage range, excellent line and load regulation, and current limit protection. It is available in an 8-pin DIP package and is suitable for use in both consumer and industrial applications. The device is ideal for use in automotive, consumer electronics, industrial, and medical industries due to its fast turn-on time and low output temperature coefficient. The device operates in a linear manner and is able to provide a constant and stable voltage output from an input voltage range of 3V to 40V.
