The LM4128CMFX-2.0 is a precision, low-dropout micropower bandgap voltage reference in a small SOT-23 surface-mount package from Texas Instruments. This high-accuracy device is designed to provide a stable 2.0V output voltage with a tight output tolerance of ±0.1% at 25°C and ±0.2% over the full operating temperature range of -40°C to 125°C.

This voltage reference is ideal for high-performance analog and digital applications where precision is key. With a low temperature coefficient of 75 ppm/°C (max) and low output noise, it maintains a stable voltage even under varying conditions, making it suitable for ADCs, DACs, and other sensitive circuits requiring a precise reference voltage.

The LM4128CMFX-2.0 operates with a supply voltage range from 2.7V to 5.5V and is capable of sourcing and sinking up to 15mA of output current. This feature, combined with a low dropout voltage of typically 60mV at a 1mA load, makes it highly versatile for battery-powered and portable applications.

In terms of power efficiency, the LM4128CMFX-2.0 boasts a quiescent current of typically 60µA, which minimizes power consumption and extends battery life in portable applications. Additionally, it features a shutdown mode that reduces current consumption to less than 1µA, further conserving energy when the device is not in active use.

The device's robust design includes short-circuit protection and thermal shutdown, ensuring reliable operation under adverse conditions. It is also RoHS compliant, meeting environmental standards for hazardous substance regulations.

Overall, the LM4128CMFX-2.0 is a trusted choice for engineers requiring a reliable and precise voltage reference. Its small form factor, combined with its high precision and low power consumption, makes it a versatile component for a wide range of electronic systems.
