MIC5203-4.0BM4

The MIC5203-4.0BM4 is a low-dropout (LDO) linear voltage regulator manufactured by Micrel Inc. This component is designed to deliver a consistent 4.0V output voltage, capable of supplying up to 80mA of current. Its low dropout characteristic is beneficial for applications where input voltage is close to the output voltage, maximizing power efficiency.

Key electrical specifications include a 4V fixed output and an 80mA maximum output current. The regulator is designed for efficient operation, particularly in power-sensitive applications. While specific dropout voltage figures are not detailed here, LDOs typically offer low quiescent current and minimal voltage drop under load.

This device is suitable for various power management tasks in electronic circuits. Its linear regulation approach ensures low output noise, making it appropriate for sensitive analog or digital systems. The component's compliance status indicates RoHS3 compliance and a Moisture Sensitivity Level (MSL) of 1, suggesting it is robust and easy to handle during assembly.

Further details regarding package type, operating temperature range, and specific performance curves would typically be found in the manufacturer's datasheet. However, based on available information, the MIC5203-4.0BM4 is a reliable choice for applications requiring a stable, low-current 4V power source.
