Description and Introduction

400mA Low-Dropout Voltage Regulator # Introducing the MIC29201-4.8WU: A High-Performance LDO Regulator for Precision Power Management  

In today’s demanding electronic applications, stable and efficient power regulation is critical. The MIC29201-4.8WU from Microchip Technology is a high-performance, low-dropout (LDO) voltage regulator designed to deliver precise and reliable power in a compact package.  

With an output voltage of 4.8V and a maximum output current of 1.5A, the MIC29201-4.8WU is ideal for powering sensitive analog and digital circuits where voltage stability is paramount. Its ultra-low dropout voltage—as low as 340mV at full load—ensures efficient operation even when input voltage margins are tight.  

Engineers will appreciate the device’s excellent line and load regulation, minimizing output voltage fluctuations under varying conditions. Additionally, the MIC29201-4.8WU features built-in protection mechanisms, including thermal shutdown, current limiting, and reverse-battery protection, enhancing system reliability in harsh environments.  

The regulator’s fast transient response makes it well-suited for high-speed applications, while its low quiescent current minimizes power loss in battery-operated devices. Available in a space-saving 5-pin TO-263 package, the MIC29201-4.8WU is an excellent choice for embedded systems, industrial controls, automotive electronics, and portable devices.  

For engineers seeking a robust, high-efficiency LDO regulator, the MIC29201-4.8WU delivers exceptional performance and reliability, making it a standout solution for precision power management.

Application Scenarios & Design Considerations

400mA Low-Dropout Voltage Regulator

Alternative Part Number

  • LM2940CT-5.0 --: Widely available 1A low-dropout linear regulator in TO-220, similar dropout and current capability; 5.0V fixed output is the closest standard voltage to 4.8V and is a common drop-in for Micrel LDOs.
  • LT1085CT-5 --: 3A low-dropout positive regulator in TO-220 with excellent load regulation and thermal performance, suitable where the MIC29201's 1A rating is not a hard limit; different series and prefix make it easy to distinguish.
  • MC33269DT-5.0G --: 800mA low-dropout regulator in DPAK/TO-252, pin-compatible with many Micrel LDO footprints and a cost-effective second source for 5V fixed-output applications.
