Description and Introduction

LOW NOISE 150mA L.D.O REGULATOR  # Introduction to the R1120N401B-TR Voltage Regulator  

The **R1120N401B-TR** is a high-performance, low-dropout (LDO) voltage regulator designed for stable power supply applications in compact electronic devices. This component is part of a series of regulators known for their low quiescent current, high accuracy, and excellent transient response, making them ideal for battery-powered and portable electronics.  

With a fixed output voltage of **4.0V**, the R1120N401B-TR ensures reliable voltage regulation even under varying load conditions. Its low dropout voltage allows efficient operation with minimal power loss, extending battery life in critical applications. The device features built-in overcurrent and thermal shutdown protection, enhancing system reliability in demanding environments.  

The regulator is housed in a **SOT-23-5** package, offering a compact footprint suitable for space-constrained designs. Its low noise output makes it well-suited for analog and digital circuits requiring clean power, such as sensors, microcontrollers, and wireless modules.  

Key specifications include an input voltage range of **1.7V to 6.0V**, a maximum output current of **200mA**, and an ultra-low quiescent current of **1.0µA** (typical) in shutdown mode. These characteristics make the R1120N401B-TR a versatile choice for IoT devices, wearables, and other energy-efficient applications.  

Engineers value this regulator for its balance of performance, size, and power efficiency, ensuring stable voltage delivery in modern electronic systems.
