Introduction

MIC5238-1.3YD5-TR are high efficiency, low noise linear voltage regulator solutions for applications where maximum efficiency, minimum noise and maximum protection are required. They are designed to provide a fixed output voltage from a wide range of input voltages with low quiescent current. Utilizing CoolMOS™ technology, these high accuracy linear voltage regulators are ideal for many high voltage fixed voltage applications.

Application Field and Working Principle

The MIC5238-1.3YD5-TR linear voltage regulator family is ideal for use in high voltage applications, such as motor control DC/DC converters, motor drive applications, automotive applications and medical systems. Their excellent thermal properties, low quiescent current and high power output make them perfect for these demanding applications.

The MIC5238-1.3YD5-TR linear voltage regulator operates by taking an input voltage and regulating it at an output voltage determined by a resistor divider. The output voltage is regulated to within 10% of the preset voltage. This high level of accuracy helps to ensure consistent operation for all system components.

The MIC5238-1.3YD5-TR linear voltage regulator has several built-in protections designed to safeguard your system. Under-voltage lockout (UVLO) is designed to protect the regulator from damage due to a sudden drop in the output voltage, which can occur in car electronics or when a boost converter supplies a voltage too low for the linear voltage regulator.

The MIC5238-1.3YD5-TR linear voltage regulator also includes a thermal shutdown (TSD) protection, which will shut the device down and latch the output voltage off until the temperature drops below the thermal shutdown threshold. This helps to ensure system stability and prevents any damage to the regulator due to excessive temperatures.

Conclusion

The MIC5238-1.3YD5-TR linear voltage regulator is an ideal solution for high voltage applications that require a high efficiency and low noise solution. Its excellent thermal properties, low quiescent current and high power output make it an ideal choice for many demanding applications. The built-in protections are designed to help safeguard your system from sudden drops in output voltage and excessive temperatures.
