The LM4051CIM3-ADJ is an adjustable bandgap reference voltage device used in power management and power conversion applications such as automotive, industrial, consumer and communications. It is an adjustable bandgap voltage reference used in voltage regulation and voltage boosting applications. It provides a reference voltage that can be adjusted over a wide voltage range and provides very low noise operation.

In many applications, such as digital power converters, the output voltage is usually monitored using an Analogue-to-Digital Converter (ADC). The voltage reference provides the maximum and minimum voltages for the ADC to read for setting the output voltage level. The LM4051CIM3-ADJ provides an adjustable voltage reference, which allows the setting of the output voltage range. This reduces the need to stock multiple voltage references when a variety of output voltages are required.

The LM4051CIM3-ADJ is a low noise, high accuracy and simple-to-use adjustable bandgap voltage reference device. It offers an output voltage that can be adjusted from 1.2V to 18V with a minimum of disturbance noise. It offers a low temperature coefficient, low output noise and high accuracy over a wide supply voltage range. The LM4051CIM3-ADJ also features a fast start-up time with no warm-up stabilization time, enabling fast and efficient operation.

The LM4051CIM3-ADJ offers a CMOS compatible dual output, where the second output is always 0.45V lower than the first output. This enables the use of the LM4051CIM3-ADJ in applications such as analog-to-digital converters, digital-to-analog converters, battery-powered systems and as a system power monitor.

The LM4051CIM3-ADJ uses a simple two-resistor voltage divider to set the output voltage. The two resistors R1 and R2 are connected together at a common node to the reference output and to set the output voltage. The current source to the resistors is broken into two stages for 1.2V to 5V operation and a single stage for 5V to 18V operation.

The LM4051CIM3-ADJ also has a power down mode, which allows the device to be powered down when the output voltage is not required. This feature allows the device to operate more efficiently while reducing the power consumption of the system.

The LM4051CIM3-ADJ is an ideal solution for voltage regulated power supplies, automotive, industrial and consumer applications. It provides simple and efficient voltage regulation with adjustable voltages, low noise operation and fast start-up time.
