Description and Introduction

Low VIN/VOUT 300mA High PSRR ULDO? with Ultra-Low IQ **Introducing the MIC5309YMT: A High-Performance LDO Regulator for Precision Applications**  

The MIC5309YMT is a high-performance, low-dropout (LDO) voltage regulator designed to deliver exceptional power efficiency and stability for modern electronic systems. Engineered for precision applications, this component offers ultra-low noise, high PSRR (Power Supply Rejection Ratio), and fast transient response, making it an ideal choice for sensitive analog and digital circuits.  

With a low dropout voltage of just 150mV at 300mA load current, the MIC5309YMT ensures efficient power conversion even when input voltages are close to the output level. Its wide input voltage range (2.5V to 5.5V) and adjustable output (0.8V to 5.0V) provide flexibility for diverse applications, including portable devices, medical equipment, and IoT modules.  

The device features a high PSRR of 75dB at 1kHz, minimizing output voltage fluctuations caused by input supply variations. This makes it particularly suitable for RF and noise-sensitive applications where stable voltage regulation is critical. Additionally, the MIC5309YMT incorporates advanced protection features such as thermal shutdown and current limiting, enhancing system reliability under adverse conditions.  

Housed in a compact 6-pin Thin DFN package, the MIC5309YMT is optimized for space-constrained designs without compromising performance. Its low quiescent current (75µA typical) further extends battery life in portable electronics.  

For engineers seeking a robust, high-efficiency LDO regulator with superior noise performance, the MIC5309YMT stands out as a dependable solution. Whether in industrial, automotive, or consumer applications, this component ensures precise voltage regulation with minimal power loss.  

Explore the MIC5309YMT for your next design and experience the benefits of high-performance power management in a compact, reliable package.

Application Scenarios & Design Considerations

Low VIN/VOUT 300mA High PSRR ULDO? with Ultra-Low IQ

Alternative Part Number

  • LP5907MFX-1.2 --: Low-noise LDO in the same tiny package class with comparable current capability and a different series naming, making it a clear drop-in style alternative.
  • TLV70212PDBVR --: Low-dropout regulator with similar output current and low quiescent current, offered in a small SOT-23 package as a practical substitute.
  • AP2112K-1.2TRG1 --: Widely available LDO regulator with comparable voltage and current ratings, suitable as a cost-effective replacement from a different series.
