In addition, the device can be used to provide power to other equipment where a regulated supply of up to 4.7 volts is required.

This power regulator utilizes a fixed output voltage of 4.7 volts, and has a programmable output voltage range of 1.5 to 4.5 volts. It is available in a variety of packages and features a wide input voltage range of 1.7 to 5.5 volts, with an output compliance of ±2%. This ensures the device will accurately deliver the desired regulated power over a wide range of applications.

The LP3985IM5X-4.7/NOPB is ideal for automotive, medical and industrial applications which require a reliable and efficient voltage regulator. It also provides protection for the device from transient overvoltages, current surges and thermal overloads.

Working Principle

This voltage regulator is based on the linear regulator principle, a process by which a linear voltage regulator uses the voltage drop across a series resistor to regulate the output voltage to a desired level. This is done by using a feedback loop which monitors the output voltage and then adjusts the current flowing through the series resistor in order to maintain the desired output voltage.

The LP3985IM5X-4.7/NOPB uses a programmable resistor, which is connected between the input and output of the device, to regulate the output voltage. The resistor is then adjusted by the voltage feedback loop in order to maintain the desired output voltage.

The linear-mode voltage regulator also features current-limit and thermal protection, which will shut the device off if it is subjected to a voltage surge or high temperatures. This provides additional safety and reliability for applications.

Conclusion

The LP3985IM5X-4.7/NOPB is an advanced, PMIC voltage regulator that is designed to provide efficient power conversion with low power loss and high accuracy. This voltage regulator is ideal for a wide range of applications, from personal computers and medical equipment to automotive systems and industrial applications. Its linear regulator principle ensures reliable power delivery with excellent load regulation and current-limit and thermal protections for enhanced safety and performance.
