Introduction

The LP5951MGX-2.8/NOPB is a Texas Instruments PMIC that is a low dropout (LDO) linear voltage regulator. It is a member of the LP5951MGX family and is optimized for extremely low-voltage applications and is designed with an output voltage of 2.8 volts and a maximum output current of 600 mA. It is a point-of-load power supply that can supply a regulated, low-noise output voltage from an external input voltage source, either a battery or a larger voltage rail.

Applications

The LP5951MGX-2.8/NOPB offers several desirable features for various applications requiring a low-voltage power supply. It is ideal for applications with a battery as the source and provides very low-noise performance due to its proprietary control loop. This feature makes the LP5951MGX-2.8/NOPB excellent for powering sensitive audio circuits and specialty components. The device also features thermal shutdown protection and output over-current protection, making it suitable for a wide range of applications.Due to its low supply current, very low 0.5µA shutdown current, and very low quiescent current of only 1.5µA, the LP5951MGX-2.8/NOPB is well-suited for low-power applications and portable devices. The high-current capabilities of this device make it well-suited for powering microcontrollers and displays, and it is also ideal for both DC to DC converters and intelligent loads.

Working Principle

The LP5951MGX-2.8/NOPB is a low drop-out linear regulator that is designed to accurately regulate the output voltage from an external source (normally a battery). It is composed of a voltage reference, an error amplifier, and a pass element. The error amplifier compares the regulated output voltage to a reference voltage and adjusts the output voltage accordingly. The voltage reference is derived from a bandgap reference circuit and is accurate over temperature and input voltage.The pass element of the LP5951MGX-2.8/NOPB is a series pass transistor, either PMOS or NMOS, which is used to provide the output current. The output current is limited by the current limit of the pass element, which can be adjustable depending on the application. The pass element is also used to provide load-line regulation, so that the output voltage is regulated even if the load current changes drastically.

Conclusion

The LP5951MGX-2.8/NOPB is an excellent low drop-out linear regulator for low-voltage applications with a low-noise performance. It is ideal for batteries, DC-to-DC converters, and intelligent loads and provides very low quiescent and shutdown currents, making it well-suited for low-power applications. It features thermal and output over-current protection and is designed to accurately regulate its output voltage.
