Working Principle

The LM4050AEX3-5.0+T is designed to provide a stable, accurate output voltage. The device utilizes a proprietary bandgap reference circuit within a TO-5 package, and is isolated from the surrounding environment. At the heart of the LM4050AEX3-5.0+T is a precision voltage reference that is temperature compensated for better performance. It also features a low offset voltage of 1 mV, which keeps the output voltage from fluctuating due to temperature, allowing it to maintain a constant output. The closed-loop architecture of the LM4050AEX3-5.0+T allows for superior voltage regulation, and is immune to power supply line noise and ripple. The voltage reference circuit uses an error-correction technique to monitor and adjust the output voltage, allowing for low thermal effort and high accuracy. The LM4050AEX3-5.0+T also features a wide input voltage range of 2V to 40V and a maximum load current of 10mA. The device is available in three package types, TO-5, TO-73 and SOIC-7, making it easy to implement into existing designs without the need for major changes. The LM4050AEX3-5.0+T is also designed to limit output current to prevent damage to components, while also featuring a low power-on reset time to ensure a smooth startup. It also has an internal regulator and built-in power-on reset circuitry to protect it from any sudden drops in power or other irregularities. Overall, the LM4050AEX3-5.0+T is an ideal voltage reference for a wide range of applications, thanks to its high accuracy, precision and low drift. Its robust design and wide input voltage range make it ideal for low power systems and embedded applications, while its low power-on reset time ensures a smooth startup. Its internal regulator and power-on reset circuitry also provide protection against sudden changes in power or other irregularities. Its versatile design and reliable performance make the LM4050AEX3-5.0+T a great choice for applications requiring precise voltage regulation and high accuracy.
