Description and Introduction

1.2A Low-Dropout Voltage Regulator # **Reliable Power Regulation with the MIC2940A-5.0WU Voltage Regulator**  

In demanding electronic applications, stable and efficient power regulation is essential. The MIC2940A-5.0WU is a high-performance linear voltage regulator designed to deliver a fixed 5.0V output with exceptional accuracy and reliability. Engineered for robustness, this regulator is ideal for industrial, automotive, and embedded systems where consistent power delivery is critical.  

With a maximum output current of 1.5A and a low dropout voltage of just 340mV at full load, the MIC2940A-5.0WU ensures efficient operation even when input voltages are close to the output level. This makes it particularly suitable for battery-powered devices and applications where minimizing power dissipation is a priority.  

The regulator features built-in protection mechanisms, including thermal shutdown and current limiting, safeguarding against overheating and short circuits. Its wide input voltage range of up to 26V enhances versatility, allowing it to handle fluctuations in power sources without compromising performance.  

Housed in a compact TO-263 (D2PAK) package, the MIC2940A-5.0WU is designed for easy integration into space-constrained designs while maintaining excellent thermal performance. Its low quiescent current further enhances energy efficiency, making it a preferred choice for power-sensitive applications.  

Whether used in automotive electronics, industrial control systems, or portable devices, the MIC2940A-5.0WU provides a dependable power solution with minimal external components required. Its combination of high current capability, low dropout voltage, and robust protection features ensures long-term reliability in even the most demanding environments.  

For engineers seeking a high-quality, fixed-voltage regulator, the MIC2940A-5.0WU stands out as a trusted solution for stable and efficient power management.

Application Scenarios & Design Considerations

1.2A Low-Dropout Voltage Regulator

Alternative Part Number

  • LM2940CT-5.0 --: Pin-compatible 5V low-dropout regulator in TO-220 with similar dropout and current rating, widely available and well documented.
  • LT1085CT-5 --: 5V LDO regulator in TO-220 with higher current capability and comparable dropout performance, suitable as a robust substitute.
  • MC7805CTG --: Standard 5V linear regulator in TO-220; lower cost and widely stocked, though dropout is higher so verify thermal and input headroom requirements.
  • L4940V5 --: 5V low-dropout regulator with similar dropout and current ratings, suitable drop-in replacement in most 5V regulator designs.
