STMicroelectronics LM336BDT Voltage Reference
The LM336BDT from STMicroelectronics is a precision 2.5V shunt voltage reference with guaranteed temperature stability over the entire temperature range of operation. It is designed to provide a stable reference voltage for high-precision electronic circuits, ensuring consistent performance and reliability in a variety of applications, including power supplies, digital voltmeters, and other analog and digital circuits that require an accurate reference voltage.
This voltage reference comes in a compact TO-220 package, making it suitable for through-hole mounting, which is beneficial for prototyping and manufacturing in applications where space is at a premium. The device features a dynamic impedance of 1 ohm, which is a measure of the stability of the reference voltage under varying load conditions. This low dynamic impedance ensures that the output voltage remains stable even with load changes, making the LM336BDT a robust choice for critical applications.
One of the key advantages of the LM336BDT is its ease of use. It can be operated with only two external resistors to set the output voltage to any value between 2.5V and the maximum supply voltage. This flexibility allows designers to customize the reference voltage to meet specific requirements without the need for additional components, simplifying the design process and reducing the bill of materials.
The device is also characterized for a wide current range from 400 µA to 10 mA, providing designers with a versatile range of operating conditions. The LM336BDT has a typical temperature coefficient of 20 ppm/°C, which ensures that the voltage reference remains precise and stable across a wide temperature range, making it ideal for temperature-sensitive applications.
In summary, the LM336BDT from STMicroelectronics is a high-quality, reliable voltage reference that combines ease of use with high precision and stability. Its robust design and flexible operating conditions make it a suitable choice for a wide range of electronic applications where accurate voltage referencing is crucial.
