Description

Unleash Precision Voltage Control with LM4040

Here, power management and excellence meet in the world of precise voltage references. Introducing the LM4040 family of bandgap circuits, your go-to source for precise micro-power voltage measurements.
The SOT23 package of the voltage reference integrated circuit (LM4040) is small and lightweight, which makes it a great option for applications where space is limited. Its special benefit is that it doesn't need an output capacitor, which makes the design simpler and guarantees accurate voltage regulation. To meet different precision requirements, the LM4040 provides three different output voltage tolerance options: ±0.2% for LM4040B, ±0.5% for LM4040C, and ±1% for LM4040D. Because of its degree of adaptability, it can easily handle a variety of voltage reference requirements.
The LM4040's superior ability to produce low-output noise and maintain stability under difficult circumstances only serves to increase its allure. Having an output noise of only 45µVRMS in the 10Hz to 10kHz frequency range, it is an excellent choice for applications that require outputs that are stable and clean.

The operating current range of the LM4040 is also very versatile, making it suitable for a broad range of applications. It can be used in battery-powered devices, precision power supplies, portable instrumentation, portable communication devices, notebook and palmtop computers, and data acquisition systems because of its ability to operate with a current range of 60µA to 15mA. In addition, its design ensures dependable performance across wide temperature ranges, up to +125°C, while maintaining a minimal temperature coefficient of 100 ppm/°C at its highest point. This model is a desirable option for many electronic systems and gadgets because it complies with contemporary environmental standards thanks to the inclusion of eco-friendly green moulding in its compact SOT23 package.

To meet a variety of requirements, it offers a range of fixed output voltage options, from 2.5V to 5.0V. These devices guarantee accurate performance with initial tolerances of 0.2% (B-grade), 0.5% (C-grade), and 1% (D-grade). These marvels, which come in small SOT23 surface mount packages, are a great option if space is at a premium. Their typical temperature coefficient is only 20ppm/°C, which is impressive. They operate efficiently in the 60µA to 15mA range. It also provides accuracy and adaptability in a compact, effective package.
