The LM4040B82IDCKR is an integrated circuit designed to maintain a relatively precise constant voltage in a variety of applications. This integrated circuit belongs to the category of PMIC (power management integrated circuits). It is a specialized voltage reference, making it a great choice for use in instruments, sensors, test & measurement and medical applications.

As a voltage reference, LM4040B82IDCKR is designed to output a reference voltage that is set by a potentiometer. The reference voltage is then used in other circuits as a point of comparison. Any changes in the reference voltage will be picked up by the other circuits and adjustments made accordingly. If the reference voltage shifts too far, it can cause misreading and other malfunctions.

The LM4040B82IDCKR is also known for its low power, high accuracy and low-voltage operation. It operates over a range of 2.98V to 5.5V, which makes it suitable for a wide variety of applications. It has a low Quiescent Current (Iq) of only 3µA and a low supply noise sensitivity of 0.06µV/V. The typical temperature coefficient is 0.12ppm/°C and the typical load regulation is 0.1%. This integrated circuit is capable of delivering up to ±50ppm for output voltage accuracy.

The reference voltage output of the LM4040B82IDCKR can be adjusted by the internal potentiometer. It also has a low-power disable mode where the output voltage can be set to 1.21V or lower. This integrated circuit also integrates Reverse Battery Protection and Overload Protection to protect the circuit from damage.

The LM4040B82IDCKR is ideal for a number of applications such as use in low power systems, battery management, automotive applications, programming external logic level converters, and data converters. It is also used in several industrial and consumer systems such as sensors, temperature switches, counters, actuators and displays. Its low power consumption and low output impedance make it a great choice for precision reference voltage applications.

In summary, the LM4040B82IDCKR is an integrated voltage reference that has a wide range of applications. It is designed to maintain a relatively precise constant voltage in a variety of applications. It has a low Quiescent Current (Iq) of only 3µA and a low supply noise sensitivity of 0.06µV/V. It is ideal for use in precision reference voltage applications, such as in low power systems, battery management, automotive applications, and data converters.
