Introduction

Voltage references are electronic circuits used to establish (and maintain) a single defined output voltage, regardless of input voltage, temperature and current variations. Usually, voltage references are employed to stabilize, calibrate and buffer an electronic system. The LM336Z-25, manufactured by Texas Instruments, is a 3-terminal adjustable voltage reference that is typically used in circuit applications that require a stable, precision output voltage. Voltage references are a vital component in any circuit, particularly in precision measurement circuitry, in order to ensure accuracy, stability and repeatability.

Application Field

The LM336Z-25 adjustable voltage reference\'s output voltage is internally regulated and can be adjusted by the output terminal and a single control terminal. This makes it simple to adjust the output voltage to any desired value over a range of -2.5 to -27 Volts. Its wide range of features make it suitable for an array of precision instrumentation and feedback types of applications.The LM336Z-25 is used for providing a stable input/output voltage in a variety of applications, such as temperature compensation, laboratory testing equipment, automotive electronics, and medical instruments. The LM336Z-25 can also be used to provide a stabilized reference voltage for D/A and A/D converters, and for providing regulated power for signal levels in test and measuring instruments.Other applications for the LM336Z-25 include precision control systems, active filters, data acquisition, signal processing, power regulation, voltage regulation, and industrial measurement and control systems.

Working Principle

The LM336Z-25 consists of a 3-terminal adjustable voltage reference, a temperature compensating Zener reference, and a series pass element. The reference output is maintained by a Zener reference element, which is a temperature compensated Zener diode connected in the collector circuit of the series pass element.The voltage output of the LM336Z-25 is adjustable by a single terminal control voltage. A maximum voltage of -27V is set by the application of a negative control voltage over the range of -2.5 to -27V. The voltage output of the LM336Z-25 is not affected by the external supply voltage or temperature variations.

Advantages

The LM336Z-25 is a valuable reference for delivering accurate output voltage levels for a variety of applications. It has a great stability over temperature and input voltage fluctuations. Also, due to its design, it has an inherent over-temperature protection that gets rid of the need for external protection circuits.The adjustable voltage output of the reference is convenient and easy to adjust. Its circuit design and compensation network allows it to maintain a stable and low-noise reference voltage with low power consumption. The LM336Z-25 is also a cost-effective solution for providing a stable reference voltage for precision electronics applications. This makes it a popular choice for a wide range of industrial applications.

Conclusion

The LM336Z-25 adjustable voltage reference from Texas Instruments is a highly reliable precision reference ideal for industrial applications, automotive electronics, temperature compensation, and laboratory testing equipment. Its adjustable output voltage can be set to any value between -27V to -2.5V, providing a stable and low-noise reference. It also has an inherent over-temperature protection, eliminating the need for external protection circuits. With its cost-effectiveness and great stability across temperature and input voltage fluctuations, the LM336Z-25 makes an excellent choice for precision electronic applications.
