Description and Introduction

1A, Ultra-Low Dropout, Ultra-Fast CMOS LDO Regulator # RT9187-28PQV: A High-Performance LDO Regulator for Precision Applications  

In today's fast-evolving electronics landscape, reliable power management is critical for ensuring optimal performance in sensitive circuits. The **RT9187-28PQV** from Richtek stands out as a high-efficiency, low-dropout (LDO) voltage regulator designed to meet the demanding requirements of modern applications.  

Engineered for precision, the RT9187-28PQV delivers a stable **2.8V output** with an ultra-low dropout voltage of just **120mV at 300mA**, making it ideal for battery-powered devices and noise-sensitive systems. Its exceptional **load and line regulation** ensures consistent performance even under fluctuating input conditions, while a low quiescent current of **60µA** enhances energy efficiency in portable electronics.  

One of the key advantages of this LDO regulator is its **fast transient response**, which minimizes output voltage variations during sudden load changes—a crucial feature for processors, RF modules, and IoT devices. Additionally, the RT9187-28PQV incorporates built-in **over-current and thermal protection**, safeguarding connected components from potential damage due to excessive current or overheating.  

Available in a compact **SOT-23-5 package**, the RT9187-28PQV is well-suited for space-constrained designs, offering a balance of performance and footprint efficiency. Its wide **input voltage range (2.5V to 6V)** further enhances versatility, supporting a broad spectrum of applications from consumer electronics to industrial systems.  

For engineers seeking a robust, high-performance LDO regulator, the RT9187-28PQV provides an excellent combination of efficiency, stability, and protection. Whether deployed in wearables, embedded systems, or communication devices, this component ensures reliable power delivery with minimal noise—an essential factor in maintaining signal integrity and system longevity.  

By integrating the RT9187-28PQV into your design, you can achieve superior power management without compromising on performance or reliability.
