A voltage reference, also known as a precision voltage reference, is a device designed to maintain a precise voltage level regardless of the changes in the applied current, temperature and other related factors. The LM236H-5.0 is a device of this kind manufactured by Texas Instruments. Let’s take a closer look at its application field, working principle and its features.

Application Field

The LM236H-5.0 is a precision three-terminal, adjustable voltage reference. It is designed to provide a stable output with higher immunity to line fluctuations, load changes and thermal variations. This device is widely used in variety of applications that require precise voltage control, such as:

• Power supply systems
• Digital-to-Analog Converters (DACs)
• Audio systems
• Motor controls
• Battery-powered devices
• Industrial process control systems
• Electronic instruments

Working Principle

The LM236H-5.0 is based on an operational amplifier (op-amp). It is designed to provide the reference voltage precisely over a wide range of temperatures. An op-amp is an integrated circuit (IC) with two inputs (negative and positive) and one output. It is a type of amplifier used for mathematical operations and to change the gain of a signal. In the case of the LM236H-5.0, the op-amp works together with two transistors to regulate the voltage.

The two transistors, often referred to as the mirror transistors, serve the purpose of providing a stabilizing output. The mirror transistors are connected in a voltage follower configuration, meaning that one is connected to the output of the other. This connection ensures that the voltage of the output follows the voltage of the input. This means that when the input voltage changes, the output voltage will follow suit and remain the same.

In the case of the LM236H-5.0, the transistors are connected to an adjustable internal resistor, which is used to change the output voltage. The adjustable internal resistance allows the user to adjust the output voltage to whatever they need. This ensures that the output voltage remains the same regardless of changes in line fluctuations, load and temperature.

Features

The LM236H-5.0 has several features that make it suitable for a wide range of applications. These features include:

• Low temperature coefficient of 0.2PPM/K
• Output voltage range of 2.4V to 10.8V
• Improved line and load regulation of 0.005%
• Low output noise of -10μV/V
• Low power consumption of 120μA max
• High accuracy and stability

The LM236H-5.0 is also designed to provide excellent surge and dropout protection, making it suitable for a wide range of applications. In addition, this device is designed to withstand voltage spikes up to 40V.

Conclusion

The LM236H-5.0 is an adjustable, three-terminal, precision voltage reference. It is designed to provide a stable output with higher immunity to line fluctuations, load changes and thermal variations. This device is suitable for a variety of applications that require precise voltage control. It also has features such as low power consumption and excellent surge and dropout protection, making it a great choice for many applications.
