Introduction to L7824CV-DG

The L7824CV-DG is a 3-terminal negative voltage regulators from the family of linear voltage regulators by STMicroelectronics. This device provides a regulated output voltage for wide-range input voltage and has a wide range of applications, as it offers many features like increased current capability and thermal protection.

Application Field

The L7824CV-DG negative voltage regulator is ideal for applications that require a regulated output voltage from a wide-range input voltage. These can range from DC motor- and servo-control systems, to those operating with varying input voltages and needing a constant voltage output. Moreover, this voltage regulator can also be used in power supplies, battery-powered systems, and AC/DC power supplies - so satisfying the needs of a wide range of applications.

Working Principle

The L7824CV-DG works on the principle of a series pass transistor, a shunt regulator and a precision reference. The series pass transistor, also known as a pass element, controlls the current that passes through the voltage regulator. This current passes through a shunt regulator, or monitor, which then compares the current with a internal reference voltage in order to regulate the output voltage. A temperature compensation circuit is used to adjust the voltage to counter any changes in temperature. The precision reference sets the output voltage according to the specifications of the device.

Characteristics and Benefits

The L7824CV-DG offers many features and benefits, including a wide range of input voltages (2V to 35V), increased current capabilities (40V to 70V) and thermal protection for heat sensitive components. Moreover, the device has an enviromentally friendly lead (Pb) free plating. Other characteristics of the device include an output pin that can be adjusted via external resistors, a low output noise of 10mV and an overload noise of 50mV. The overload noise is greatly reduced thanks to the device\'s short-circuit current protection level. This has the added benefit of reducing operational losses and increasing the regulator\'s efficiency.

Conclusion

The L7824CV-DG voltage regulator offers a reliable and a wide range of applications. It is an ideal choice for those applications that require a regulated output voltage from a wide-range input voltage. The device offers many features, such as increased current capabilities, thermal protection, an adjustable output pin and low output noise. The regulator is also enviromentally friendly due to its lead (Pb) free plating.
