Description and Introduction

1A Low Dropout Positive Regulator 4-SOT-223 0 to 125 **Introducing the REG1117-3.3G4: A Reliable LDO Voltage Regulator for Precision Applications**  

In today’s fast-evolving electronics landscape, stable and efficient power management is critical. The **REG1117-3.3G4** from Microchip Technology stands out as a high-performance, low-dropout (LDO) voltage regulator designed to deliver a fixed 3.3V output with exceptional accuracy and low noise.  

Engineered for versatility, the REG1117-3.3G4 is ideal for a wide range of applications, including embedded systems, IoT devices, portable electronics, and industrial controls. With a dropout voltage as low as **1.1V at 800mA**, it ensures reliable performance even when input voltages are close to the output level, maximizing efficiency in battery-powered designs.  

Key features include a **tight output voltage tolerance of ±1%**, ensuring precision for sensitive analog and digital circuits. Its low quiescent current and thermal shutdown protection enhance energy efficiency and safeguard against overheating, making it suitable for power-sensitive and high-reliability applications.  

The regulator’s **high PSRR (Power Supply Rejection Ratio)** minimizes noise interference, providing clean and stable power to critical components. Available in a compact **SOT-223 package**, it offers excellent thermal performance while saving board space—an advantage for modern, miniaturized designs.  

Whether you're developing consumer electronics, medical devices, or industrial automation systems, the **REG1117-3.3G4** delivers dependable voltage regulation with minimal external components, simplifying design and reducing costs. Its robust performance and ease of integration make it a preferred choice for engineers seeking efficiency without compromise.  

For designs demanding precision, efficiency, and reliability, the **REG1117-3.3G4** is a proven solution that meets the challenges of today’s power management needs.

Application Scenarios & Design Considerations

1A Low Dropout Positive Regulator 4-SOT-223 0 to 125

Alternative Part Number

  • LM1117IMPX-3.3 --: Pin-compatible 3.3V LDO regulator in SOT-223 with similar dropout and current rating, widely available and often used as a direct substitute.
  • AMS1117-3.3 --: Low-cost 3.3V LDO in the same package family with comparable 800mA output, commonly used as a drop-in replacement in many designs.
  • LD1117S33TR --: 3.3V fixed LDO regulator with similar electrical characteristics and SOT-223 package, suitable alternative from a major manufacturer.
