LM4128BMFX-3.3/NOPB is a three-terminal voltage reference that is specifically designed for applications requiring low-noise and low-drift voltage regulation. It is a monolithic device that is built using a bandgap reference using CMOS technology. LM4128BMFX-3.3/NOPB is an excellent choice for use in a wide variety of applications, such as low-noise power supply regulation, automotive electronics, precise instrumentation, telecommunications, microprocessors, A/D, and D/A converters.

The main features of the LM4128BMFX-3.3/NOPB include a single 3.3V output voltage that is accurate to within ±0.2% of its nominal value, high accuracy and precision output levels, temperature stabilized voltage, temperature drift of only 0.01 %/°C, low noise of 0.1mVrms at 1kHz, and a low supply current of 10mA. The device also has high current capability and is able to sink or source up to 400mA. It can operate on a supply voltage range of 2.7V to 12V, and it also has a dropout voltage of 200mV (at 200mA).

In addition, LM4128BMFX-3.3/NOPB also has a wide range of protection features that make it ideal for use in harsh environments. It has over-temperature protection, under-voltage shutdown, and thermal protection that prevent the device from overheating or being damaged due to changes in the operating environment. The device also has a high input voltage range of up to 20V and is capable of operating in a wide range of temperatures from -40°C to 105°C.

The working principle of LM4128BMFX-3.3/NOPB is based on the use of a bandgap reference. This is a voltage reference circuit that essentially exploits the fact that the voltage developed across a diode junction is relatively unaffected by changes in temperature. The bandgap reference is then used to create a voltage reference by measuring the voltage across the diode junction and then correcting this voltage by a gain that is proportional to the temperature coefficient of the diode. This corrected voltage is then used as the reference voltage for the device.

To ensure the accuracy of the reference voltage, the device uses a laser trimming process to calibrate the voltage output over a wide operating temperature range. This laser trimming process allows the output voltage to remain very stable over its entire operating range, while also providing excellent accuracy. This process also reduces the noise generated by the device as it is constantly monitoring the voltage output and compensating for any changes.

Because of its high accuracy and precision output levels, wide operating temperature range, low noise and low drift, the LM4128BMFX-3.3/NOPB is an excellent choice for applications where accuracy and reliability are of the utmost importance. This device is also well-suited for applications that require low supply current, and for environments that require protection from over-temperature or under-voltage shutdown. The LM4128BMFX-3.3/NOPB is well-suited for use in a wide variety of applications, such as low-noise power supplies, automotive electronics, precise instrumentation, telecommunications, microprocessors, A/D and D/A converters.
