Description and Introduction

400mA Low-Dropout Voltage Regulator # MIC2920A-12WS: High-Performance Voltage Regulator for Reliable Power Management  

In today’s demanding electronic applications, stable and efficient power regulation is essential. The MIC2920A-12WS is a high-performance, low-dropout (LDO) voltage regulator designed to deliver precise 12V output with exceptional reliability. Engineered for robustness, this component ensures consistent performance in industrial, automotive, and embedded systems where power integrity is critical.  

Featuring an ultra-low dropout voltage of just 600mV at full load, the MIC2920A-12WS maximizes efficiency even when input voltages are close to the output level. Its wide input voltage range of up to 26V makes it suitable for diverse applications, while its high output current capability of 1.5A supports power-hungry circuits without compromising stability.  

Built with advanced protection mechanisms, the MIC2920A-12WS includes thermal shutdown, current limiting, and reverse-battery protection, safeguarding both the regulator and downstream components from potential damage. Its low quiescent current minimizes power loss in standby modes, making it ideal for battery-operated devices.  

Housed in a compact TO-263 (D2PAK) package, the regulator offers excellent thermal performance, ensuring reliable operation under high-load conditions. Whether used in automotive electronics, industrial control systems, or telecommunications equipment, the MIC2920A-12WS delivers dependable voltage regulation with minimal external components.  

For engineers seeking a durable, high-efficiency LDO regulator, the MIC2920A-12WS stands out as a proven solution for maintaining stable power delivery in even the most challenging environments.

Application Scenarios & Design Considerations

400mA Low-Dropout Voltage Regulator

Alternative Part Number

  • LM2940CT-12 --: 12V low-dropout linear regulator in TO-220, widely available and functionally similar to the MIC2920A-12WS.
  • LT1086CT-12 --: 12V LDO regulator with comparable current capability and dropout performance, suitable drop-in for many MIC2920A applications.
  • MC7812BTG --: Standard 12V linear regulator in TO-220; higher dropout than the original but a common, low-cost alternative when dropout is not critical.
