Introduction
LP3874EMPX-2.5 is a linear integrated circuit (IC) designed for power management in handheld and portable devices. It belongs to the family of voltage regulators commonly referred as PMIC – Voltage Regulators – Linear.It is a low-power, low-dropout, low-noise voltage regulator with a wide range of operating current from 10mA to 500mA, a minimum of 2.2V and a maximum dropout voltage of 1.2V. LP3874EMPX-2.5 is specially optimized for low power consumption and excellent noise performance with an on-chip voltage reference and wide bandwidth loop response.Application Field
LP3874EMPX-2.5 is used in automotive, digital home, healthcare, industrial, and medical applications, as well as storage and self-booting application designs. When it comes to automotive applications, it offers superior EMC performance, making it suitable for 48V to 12V power supply and charging systems. It is a perfect choice for automotive, portable, and handheld applications that require low power, low-dropout, and low-noise solutions. The applications of LP3874EMPX-2.5 include voltage regulators, output voltage tracking, LED flash drivers, LED drivers, power supplies and much more. Working Principle
The LP3874EMPX-2.5 voltage regulator features a proprietary low-power PMOS pass transistor with a high capability to deliver current, low-dropout voltage, low output noise, and excellent thermal stability and performance.The regulator converts the input voltage, which is greater than the output voltage, to a specific output voltage, depending on the voltage reference built into the control circuitry. When the input voltage rises, the control circuitry reduces the current passing through the pass transistor, thereby reducing the output voltage.The LP3874EMPX-2.5 works on the principle of pass transistor linear regulator, the input voltage is controlled by a regulating CMOS circuit and the output is maintained by an N-channel MOSFET. The voltage regulator also has an inbuilt current limit circuit and an output various voltage regulators.Conclusion
LP3874EMPX-2.5 is a low-power linear voltage regulator designed for power management in handheld and portable devices. It is very suitable for applications with low power, low-dropout and low-noise requirements such as automotive, digital home, healthcare, industrial, and medical applications, as well as storage and self-booting application designs. Its primary application is to convert a higher input voltage, which is greater than the output voltage, to a specific output voltage. Its working principle involves using an inbuilt current limit circuit and various voltage regulating by a regulating CMOS circuit and output is maintained by a N-channel MOSFET.
