TPS77825PWP

Introduction

TPS77825PWP is a linear voltage regulator, which is part of PMIC (Power Management IC). It’s designed to protect and boost the energy efficiency and thermal dissipation of the system while maintaining excellent performance with low output noise. By using linear voltage regulation and post-regulation filtering, the TPS77825PWP is suitable for a wide range of applications.

Application Field

TPS77825PWP is mainly used for processors, such as Advanced RISC Machine (ARM) processors and x86 processors, which require a lower cost and lower power consumption for powering MCUs and SoCs. It is also widely used in automotive applications, such as automotive Lighting Control and Automotive Infotainment.

TPS77825PWP can also be used for system power management in the industrial sector. It can provide high-density and high-efficiency power solutions for Industrial PCs, Factory Automation Equipment, AC/DC and DC/DC Power Supplies, Robotics, and Medical Equipment.

Working Principle

The TPS77825PWP is designed using a linear voltage-regulator topology that maintains excellent current- and voltage-regulation performance under light or heavy load conditions. It employs an internal pass element – i.e., a transistor – to regulate the output voltage. This transistor is also known as a linear regulator, as it keeps the output voltage stable by monitoring and regulating the input-output voltage differential within a predetermined range.

The TPS77825PWP utilizes a low-dropout (LDO) regulator design, which is more efficient than standard linear regulator designs. By using an LDO design the voltage regulator consumes less power, produces less heat and has higher efficiency. The TPS77825PWP supports line and load-transient regulations and can provide a fast response time to step loads.

The TPS77825PWP also supports overcurrent, over-voltage and over-temperature protection. Overcurrent protection (OCP) protects the system by limiting the output current when a short circuit is detected. Over-voltage protection (OVP) protects the system from excessive output voltage, while over-temperature protection (OTP) limits the thermal impact on the system.

Conclusion

The TPS77825PWP is a linear voltage regulator that can be utilized for a variety of application fields, from automotive to industrial. It is designed with an internal pass element and low-dropout topology, which ensures excellent performance, high-efficiency, and low-power consumption. It also features overcurrent, over-voltage, and over-temperature protection, which protects your system from potential damage. All in all, the TPS77825PWP is a reliable and efficient linear voltage regulator.
