Description and Introduction

μCap? 80mA Low-Dropout Voltage Regulator **Introducing the MIC5203-3.8BM4: A High-Performance LDO Regulator for Precision Applications**  

The MIC5203-3.8BM4 is a high-performance, low-dropout (LDO) voltage regulator designed to deliver stable and efficient power management in a compact form factor. With an output voltage of 3.8V and a maximum current capability of 150mA, this regulator is ideal for applications requiring precise voltage regulation with minimal power dissipation.  

Engineered for reliability, the MIC5203-3.8BM4 features an ultra-low dropout voltage, ensuring consistent performance even when the input voltage approaches the output level. Its low quiescent current makes it particularly suitable for battery-powered devices, extending operational life while maintaining efficiency.  

The device incorporates advanced protection mechanisms, including thermal shutdown and current limiting, safeguarding both the regulator and the connected circuitry from potential damage due to overloads or excessive temperatures. Additionally, its fast transient response ensures stable operation in dynamic load conditions, making it a dependable choice for sensitive electronics.  

Housed in a space-saving SOT-223 package, the MIC5203-3.8BM4 is optimized for applications where board space is at a premium. Its robust design and high accuracy (±2% output voltage tolerance) make it well-suited for use in portable devices, embedded systems, and precision analog circuits.  

Whether deployed in medical instruments, IoT modules, or industrial control systems, the MIC5203-3.8BM4 delivers reliable power regulation with minimal external components, simplifying design integration while enhancing performance. For engineers seeking a compact, efficient, and dependable LDO solution, this regulator stands out as a superior choice.

Application Scenarios & Design Considerations

μCap? 80mA Low-Dropout Voltage Regulator

Alternative Part Number

  • LP2985AIM5-3.8 --: Low-dropout linear regulator with 3.8V fixed output in SOT-23-5, similar current capability and pinout, widely available and well documented.
  • AP2112K-3.8TRG1 --: 3.8V fixed LDO regulator in SOT-23-5 with low dropout and low quiescent current, suitable drop-in replacement for small load applications.
  • MCP1700T-3802E/TT --: 3.8V fixed LDO in SOT-23-3 with ultra-low quiescent current; pin count differs so layout adjustment is needed, but it is a solid low-power alternative.
