Description and Introduction

1.0 A Low-Dropout Positive Fixed and Adjustable Voltage Regulators The **NCP1117DT20** is a popular low-dropout (LDO) linear voltage regulator designed to deliver stable and reliable power in a wide range of electronic applications. With a fixed output voltage of 2.0V, this regulator ensures precise voltage regulation while maintaining low power dissipation, making it an efficient choice for battery-powered devices and embedded systems.  

Built with advanced semiconductor technology, the **NCP1117DT20** offers a dropout voltage as low as 1.2V at full load, enhancing energy efficiency. It supports a maximum output current of 1A, providing sufficient power for microcontrollers, sensors, and other low-voltage circuits. The device includes built-in thermal shutdown and current-limiting protection, safeguarding against overheating and short-circuit conditions.  

Housed in a compact **TO-252 (DPAK)** package, the regulator is suitable for space-constrained designs. Its robust performance and ease of integration make it ideal for consumer electronics, industrial controls, and automotive applications where stable voltage regulation is critical.  

Engineers favor the **NCP1117DT20** for its reliability, low noise output, and cost-effectiveness, ensuring consistent performance in demanding environments. Whether used in prototyping or mass production, this regulator remains a dependable solution for maintaining steady power delivery.

Application Scenarios & Design Considerations

1.0 A Low-Dropout Positive Fixed and Adjustable Voltage Regulators

Alternative Part Number

  • LM1117DT-2.0 --: Pin-compatible 2.0V low-dropout linear regulator in the same DPAK package with equivalent current rating and dropout performance.
  • AMS1117-2.0 --: Widely available 2.0V LDO regulator with similar electrical characteristics and DPAK footprint, suitable as a drop-in replacement in most designs.
  • LD1117DT20 --: 2.0V fixed LDO regulator in DPAK with comparable dropout voltage and output current, offering a different series as a reliable alternative.
