TLE2426CDR

Introduction

TLE2426CDR is a series of shunt regulators by Microchip. This series consists of a low cost, low noise CMOS Voltage Reference, whose purpose is to define an accurately regulated voltage. In a linear voltage regulator, the output voltage can be affected by changes in current or temperature, while a TLE2426CDR is an improved shunt regulator that ensures a stable voltage without reacting to these conditions. The TLE2426CDR can be used to generate a voltage that can serve many different applications.

Application Field

The TLE2426CDR can be used in a variety of applications. It is often used as a precision reference in devices such as power supplies and battery chargers, as well as in other analog and digital circuits. It can also be used to maintain a precise voltage across a power rail in order to produce a precise constant current output from a processor or integrated circuit. Furthermore, the TLE2426CDR is useful for precise voltage control in motor controllers, as well as in power management and logic systems, with precise voltage regulation.

The TLE2426CDR is also used in instrumentation and medical devices, where precise voltage adjustments are essential. It is also used in automotive applications, where precise voltage references are necessary for safety and reliability. In addition, it may be used in other applications where precision voltage control is required, such as communication and wireless networks.

In addition to its ability to provide a precise reference voltage, the TLE2426CDR has been designed to be efficient, with a low quiescent current to reduce power consumption. This makes it an ideal choice for low power applications, and the flexible design of the TLE2426CDR allows it to be used in a variety of different systems.

Working Principle

At the heart of the TLE2426CDR is a low-noise CMOS precision voltage reference. It works by taking a reference voltage from an external circuit, and using it to compare to an internal reference voltage. If the two voltages are equal, the TLE2426CDR will apply a shunt regulator between the two voltages to maintain a constant output voltage.

The device also contains other circuitry to ensure a stable output voltage. A temperature compensation circuit is included that adjusts the output voltage depending on the ambient temperature, and a current limiter is included to protect the device from overloads. Additionally, there is a voltage limiter which ensures a safe upper limit is never exceeded.

The TLE2426CDR also has an adjustable gain to fine tune the output voltage, as well as an adjustable hysteresis voltage, which can be configured to ensure a very accurate output voltage. The device is also designed with a low supply current to reduce power consumption.

Conclusion

The TLE2426CDR is a versatile, low powered CMOS Voltage Reference suitable for use in many different applications, from instrumentation and motor controllers, to power supplies and wireless networks. Its accuracy and low power consumption make it an ideal choice for any application requiring precise voltage control. Its adjustable gain and hysteresis also allow for fine tuning of the output voltage, making it a very reliable and versatile voltage reference.
