The regulators have a low quiescent current of 230 μA and a maximum output current of ±100 mA and offer an output ripple of only 0.5 mVrms. They provide low drop-out protection, and theiroutput voltage is adjustable over a wide range. Additionally, they provide a wide temperature range of -40°C to +125°C, making them ideal for automotive and industrial applications.

Important Applications

The MMPF0100FBANES voltage regulators are especially suitable for automotive and industrial applications, where they can provide low drop-out voltage and robust protection to increase system efficiency and reliability. They also provide higher system reliability than many other linear regulators, as they have wide temperature and input range capabilities.

Working Principles

The MMPF0100FBANES regulators are low-drop-out (LDO) linear regulators. They provide stable, regulated output voltage over a wide range from 3.0 V to 40 V, with an output ripple of 0.5 mVrms. The regulators effectively convert a higher input voltage to a lower output voltage. This conversion is achieved by connecting an output transistor to the input voltage, and a reference voltage to the output transistor\'s base. The output current is regulated by the NPN bipolar output transistor.This output transistor acts as a current source, allowing a low and stable output voltage to be achieved even with large changes in the input voltage. By controlling the current flow in the output transistor, the output voltage is regulated to the required value. The voltage and current flow are monitored and the adjustment is made accordingly.

Conclusion

The MMPF0100FBANES is a low-drop-out linear regulator designed for automotive and industrial applications. It is suitable for providing the necessary current and voltage parameters for a wide range of voltage and current applications. Its wide operating temperature range of -40°C to +125°C and low quiescent current of 230 μA make it ideal for portable electronics. Additionally, its low drop-out protection, wide input range, and adjustable output voltage make it suitable for many applications. Its reliable, robust performance and low output ripple ensure system efficiency and reliability, making it a great choice for automotive and industrial applications.
