The LP2980IM5-4.7 is a linear voltage regulator from the collection of power management integrated circuits (PMICs). It features a low dropout voltage of only 0.4 V, making it an ideal choice for providing power to low power processor-based systems. Additionally, the LP2980IM5-4.7 has good line and load regulation characteristics and a very low quiescent current of only 70uA.

The LP2980IM5-4.7 is a low voltage regulator, which has an output voltage of 4.7 volts and can accept an input range of 2.7V to 6.0V. It is designed to provide power to low power applications, such as microcontrollers, FPGAs and other sensitive loads.

The working principle of the LP2980IM5-4.7 is as follows. A pass element composed of an N-channel MOSFET is connected between the input and output. The control element uses an error amplifier with a high gain in order to detect any deviations from the set point and to adjust the bias current to the MOSFET. This current, in turn, sets the voltage on the MOSFET and, hence, sets the output voltage of the regulator. The integration of the error amplifier and the MOSFET inside one integrated circuit reduces the area taken up and simplifies the use of the regulator.

The LP2980IM5-4.7 is ideal for applications that require a low voltage, low noise and high efficiency linear voltage regulator. It is commonly used for embedded systems and portable devices, such as digital cameras, GPS units, PDAs and mobile phones. Additionally, it is well suited for automotive applications where low power, low noise and high efficiency are required.

The LP2980IM5-4.7 is also a great choice for applications where safety and reliability are critical, as it offers thermal shutdown protection and short circuit protection. Additionally, the device is fully specified over both its extended temperature range, meaning that it can be used in harsh operating environments.

In conclusion, the LP2980IM5-4.7 is an ideal choice for low power, low noise and high efficiency linear voltage regulator applications. Its wide input voltage range, good line and load regulation characteristics and thermal protection make it a great choice for applications that require robust performance and reliability.
