Power management integrated circuits (or PMICs) provide a wide range of functions necessary for all modern electronic systems. This includes voltage regulation, power conditioning, and power sequencing. Voltage reference devices are a crucial component of PMICs. The LM4128DMFX-2.5/NOPB, from Texas Instruments, is a voltage reference device designed for use in these PMICs.

The LM4128DMFX-2.5/NOPB is a dual-channel, low-noise, precision voltage reference device. Its purpose is to accurately rectify, monitor, and control voltage levels in a PMIC. The device offers high accuracy and low temperature drift, with a maximum error of ±0.25%. It also provides two independent voltage reference outputs, allowing users to implement two independent voltage references in their system.

The LM4128DMFX-2.5/NOPB has two operating modes. The first is a fixed precision low-noise mode, which is suitable for DC/DC converter applications. This mode provides a stable reference voltage with minimal artifacts, allowing for optimal voltage regulation. The second is a self-biasing mode, which is suitable for applications that require an adjustable reference voltage. This mode is useful for applications such as chargers and hot-plug controllers.

The device\'s operating characteristics make it well-suited for a variety of applications. These include DC/DC converter control and rail applications, battery management control, and imaging applications. It is also suitable for hot-plug power applications and voltage level translation. Furthermore, due to its high accuracy and low temperature drift, the LM4128DMFX-2.5/NOPB is also suitable for applications where precision is of the utmost importance.
