Application Field and Working Principle of MIC5301-2.8YD5-TR

The MIC5301-2.8YD5-TR is a linear voltage regulator, which is suitable for providing a regulated output voltage for low-voltage applications. It offers excellent accuracy, low dropout voltage, low noise, and low temperature drift. It is especially suited for powering low-current linear circuits, audio applications and keeping microprocessors and digital logic in reset.The MIC5301-2.8YD5-TR is a three-terminal adjustable device that is able to provide an output voltage from 0.8V to 15.0V, with accuracy of ±2.5%. It is designed for use in low voltage circuits, such as mobile phones, notebook computers, PDAs, etc.The MIC5301-2.8YD5-TR voltage regulator works by comparing an internal reference voltage (Vref) with the output voltage (Vout). When the output voltage is greater than the reference voltage, an internal switch opens and the current is diverted away from the output and towards the ground. When the output voltage is lower than the reference voltage, the switch closes and current is diverted back to the output. The amount of current diverted is determined by the voltage difference between the reference voltage and output voltage. This current-limiting circuit prevents excessive current from flowing through the regulator. The output voltage is then maintained at the set value.

Conclusion

The MIC5301-2.8YD5-TR is a low-power linear voltage regulator ideal for powering low-voltage, low-current linear circuits. It provides an output voltage that is accurate within ±2.5% of the desired voltage and has excellent noise, low-temperature drift, and low dropout characteristics, making it perfect for applications where noise requirements are stringent.
