Description and Introduction

Ultra-Low Quiescent Current, 150mA uCap LDO Regulator # **Introducing the MIC5238-1.1BM5: A High-Performance LDO Voltage Regulator**  

The **MIC5238-1.1BM5** is a high-performance, low-dropout (LDO) voltage regulator designed to deliver stable and efficient power management for a wide range of electronic applications. With a fixed output voltage of **1.1V**, this compact regulator ensures precise voltage regulation while minimizing power dissipation, making it an ideal choice for battery-powered devices, embedded systems, and portable electronics.  

Engineered for reliability, the **MIC5238-1.1BM5** features an ultra-low dropout voltage, enabling operation even when the input supply is very close to the output voltage. This capability enhances efficiency, particularly in low-voltage applications where power conservation is critical. The device supports a **150mA output current**, providing sufficient power for microcontrollers, sensors, and other low-power components.  

One of the standout features of this regulator is its **low quiescent current**, which minimizes power loss during standby or light-load conditions. Additionally, the **MIC5238-1.1BM5** incorporates built-in protection mechanisms, including thermal shutdown and current limiting, ensuring safe operation under fault conditions.  

Housed in a **SOT-23-5 package**, the regulator offers a compact footprint, making it suitable for space-constrained designs. Its fast transient response ensures stable performance even under dynamic load changes, further enhancing system reliability.  

Whether used in IoT devices, medical electronics, or industrial control systems, the **MIC5238-1.1BM5** provides a dependable power solution with minimal external components required. Its combination of efficiency, stability, and robustness makes it a preferred choice for engineers seeking a high-quality LDO regulator.  

For applications demanding precise voltage regulation with low power consumption, the **MIC5238-1.1BM5** delivers exceptional performance in a small, cost-effective package.

Application Scenarios & Design Considerations

Ultra-Low Quiescent Current, 150mA uCap LDO Regulator

Alternative Part Number

  • LP2985AIM5-1.1 --: Low-dropout linear regulator in SOT-23-5 with fixed 1.1V output, similar current capability and pinout, widely available and well documented.
  • TPS76311DBVR --: 1.1V fixed LDO regulator in SOT-23-5 package with low quiescent current, suitable drop-in style replacement for small 1.1V rail applications.
  • AP2112K-1.1TRG1 --: Low-noise 1.1V LDO in SOT-23-5 with good load transient response, a practical alternative when the original Micrel part is unavailable.
  • TLV70211PDBVR --: 1.1V fixed-output LDO in SOT-23-5 with low quiescent current and good stability, suitable drop-in replacement for low-power applications.
