MIC29201-5.0WT

PMIC - Voltage Regulators - Linear

MIC29201-5.0WT is a component of the low dropout (LDO) voltage regulator product line developed by Shanghai Micro Market. This device offers a programming range of 2.9V to 5.5V and is designed to provide stable power supply with low power dissipation and high current output. The overall purpose of the voltage regulator is to maintain the output voltage at a slightly lower level than the input voltage while still allowing adequate current to the load.

Application Field

The MIC29201-5.0WT device is used mainly in portable digital devices, including mobile phones, tablet PCs, and other consumer electronic products as well as in industrial equipment. This component also works excellent for automotive applications and for powering field-programmable gate arrays (FPGAs). The extended range of output voltage and current capability makes the device suitable for a variety of medium and low power applications.

Working Principle

The voltage regulator functions by controlling the current passing through the load. When the input voltage increases, the upper (positive) and the lower (negative) transistors of the regulator begin conducting in turn. The current passing through the regulator is then limited depending on the load current, allowing the output voltage to be maintained at a slightly lower level than the input voltage. The main feature of the device is its low voltage dropout characteristic, which enables it to maintain a stable power supply with high output current.

The device also offers additional features such as over-current protection, thermal shut down and under-voltage lockout. This provides excellent performance and safety measures for equipment powering applications. The MIC29201-5.0WT also provides adjustable output voltage and current ratings, allowing custom designs. As a result, the device is very suitable for high power and medium power configurations.
