Voltage references, also known as voltage regulators, are integrated circuit devices used to provide a consistent voltage level to components. The LM4120IM5X-2.0/NOPB is one such device designed for applications in ultra-low-power and low-noise voltage reference applications. The device is designed for a range of applications such as providing a stable output voltage for a given application, regulating the voltage level of signals, and providing reference voltage for voltage-controlled oscillators and other analog circuits.

The architecture of the LM4120IM5X-2.0/NOPB includes an On-Board-Low-Noise-Low-Power-Voltage-Reference (OB LP VR) and a sense-resistor. The OB LP VR is typically supplied with a Vcc voltage within a range of 2-3.3V. The output voltage is internally adjusted to fit the application requirements and is set with an external resistor. The OB LP VR provides a stable output voltage that is adjustable over a wide range of output voltages.

The sense-resistor is connected from OUT to GND and senses the current flowing in the OB LP VR. The sense-resistor is used to provide a proportional output voltage in response to current flowing through the device. This output voltage is used to regulate the voltage of the device, ensuring a consistent output voltage. The sense-resistor is also used to maintain current-limit conditions in the OB LP VR by limiting the current that flows through it.

The OB LP VR provides a low-noise and low-power reference voltage while the sense-resistor ensures that the output voltage remains constant over a wide range of output voltages. Additionally, the sense-resistor ensures that the current flowing through the device is limited, improving the overall system efficiency. This feature makes the device suitable for use in ultra-low-power and low-noise systems.

The LM4120IM5X-2.0/NOPB is a versatile voltage reference and is targeting power management integrated circuit (PMIC) applications, particularly those requiring ultra-low-power and low-noise performance. The device has an excellent temperature tracking performance and is ideal for applications such as temperature sensing, precision voltage reference, voltage-controlled oscillators, and more. Additionally, the device is suitable for use in circuits with a wide range of input voltages.

The LM4120IM5X-2.0/NOPB is capable of providing an accurate voltage reference for different applications. The device has an on-board sense-resistor, which ensures consistently accurate performance over a wide range of outputvoltages. Additionally, the device is designed for ultra-low-power and low-noise voltage reference applications, making it an ideal choice for power management integratedcircuit (PMIC) applications requiring these characteristics.
