The LM4040CIM3-3.0/NOPB is an adjustable voltage reference, belonging to the group of power management and integrated circuits (PMICs). It is designed for the purpose of providing a stable and accurate voltage reference for multiple applications which require precision output voltage levels.

The LM4040CIM3-3.0/NOPB can be used in a wide variety of applications, including high-density and high-speed analog-to-digital conversion, microphone signal processing, DC to DC converters, power conditioning, regulated power supplies, and voltage signal conditioning. It is an especially suitable solution for use with high-efficiency voltage regulators such as buck, boost, and flyback designs.

The key features of the LM4040CIM3-3.0/NOPB include a programmable 3V to 25V output voltage range, accuracy of ±0.05% over the entire range, a bandwidth of 0-2.5GHz, a high power supply rejection ratio of at least 60dB, and a low temperature coefficient of ±50ppm/°C. This makes it an ideal choice for use in crystal oscillators and precision data acquisition systems. It also has an adjustable over-voltage protection of up to 120V and reverse-bias protection of up to 250V.

The operating principle of the LM4040CIM3-3.0/NOPB is based on the use of an amplifier to control the output voltage. An input voltage is adjustable with a voltage divider and fed to the amplifier, which in turn feeds back to the adjustable resistor to control the output voltage. This feedback control is regulated so that the output voltage is held in equilibrium and remains stable to changes in the input voltage or current. The output voltage is adjustable over a range of up to 25V, and the input voltage can be up to 300V.

The LM4040CIM3-3.0/NOPB can also be used in low-noise applications with precision power supplies, digital potentiometers, switching converters, and pulse-width modulation circuits. Its low-power and low-noise operation also make it an excellent candidate for use in audio amplifiers and PWM controllers. In addition, its 0.03°C/W thermal resistance allows for efficient operation in applications with high current and temperature requirements. Other features of the LM4040CIM3-3.0/NOPB include its wide input voltage range from 2V to 32V and 0.015% accuracy over the -10°C to +85°C temperature range. It is also available in 5-pin SOT-23 and 8-pin SOIC packages.

The LM4040CIM3-3.0/NOPB simplifies the design and implementation of voltage reference circuits while offering excellent performance over a wide temperature range. With its adjustable output voltage range of 3V to 25V and consistent accuracy, this device is perfectly suited for a variety of applications requiring high current, precision output voltage levels, or high power supply rejection. Its low temperature coefficient and wide bandwidth make it an ideal choice for use in precision data acquisition systems, crystal oscillators, and audio amplifiers.
