MIC39102YM-TR Introduction

In today’s electronic systems, power control is a key part of making sure they work well and are reliable. Smartphones, Internet of Things (IoT) devices, automotive electronics, and industrial tools all need efficient power conversion to power their different parts and keep things running smoothly. In the wide range of voltage regulators that are available, the MIC39102YM stands out as a flexible and efficient option that combines a small size, a high current output, and great performance.

Introducing the MIC39102YM

The MIC39102YM is a remarkable linear voltage regulator with a low dropout that is made to meet the demanding power management needs of current electronic systems. This regulator has a small size but can put out a lot of power. This gives engineers and designers a lot of benefits.

● Compact size and space efficiency

The MIC39102YM is perfect for applications where room is limited because it is small. As electronic products get smaller and smaller, it’s important to be able to combine power management components into a small package. The MIC39102YM’s small package makes it easy to use in designs with limited space without sacrificing efficiency.

● High current output

Many modern electronic systems need a high current output to run many parts at the same time. This need is met by the MIC39102YM, which is very good at delivering up to 1 A of current. This high current capability makes sure that even power-hungry devices get a stable and reliable power source, preventing voltage drops and performance degradation.

● Efficient power conversion

Efficiency is a key part of power management because it directly affects how long a battery lasts, how well heat is removed, and how well the system works as a whole. The MIC39102YM is very efficient because its dropout voltage, which is usually 410 mV at 1 A, is low. This means that even if there is only a small change in voltage between the input and output, the regulator can still convert power efficiently, reducing energy loss and making the battery last as long as possible.

Overview of the MIC39102YM: Empowering Efficient Voltage Regulation

The MIC39102YM is a high-performance, low-dropout linear voltage regulator made to meet the demanding power control needs of modern electronic systems. Because it has a low dropout voltage and a low ground current, engineers and designers can use it to convert power in a safe and efficient way.

Low Dropout Voltage

The MIC39102YM stands out because it has a very low dropout voltage. This means that the output is stable and accurate even when the difference between the input and output voltages is small. This makes it easier to convert power and waste less energy, which makes it perfect for battery-powered products.

Low Ground Current

The MIC39102YM uses less power and keeps the battery alive longer because it has a low ground current. It makes sure that power gets to all the parts and that their performance stays stable.

Options for Packages

The MIC39102YM comes in two different packages to meet different needs:

  • MIC39100 is a small SOT-223 package for designs with limited room.
  • MIC39101/MIC39102: 8-lead SOIC package with improved thermal performance, which makes it work reliably in tough conditions.
  • The different package choices give system integration flexibility, taking into account size and heat issues.

Applications: Harnessing the Versatility of MIC39102YM

The MIC39102YM is a voltage regulator that is very flexible and works well in a wide range of situations. One place where it works especially well is on PC add-in cards that need to change the power. Let’s look at how this regulator can be used and what it can do for you in different voltage-switching situations.

● Add-in cards for PCs

A lot of the time, PC add-in cards need to change volts to make sure they work well together and that the power is managed well. The MIC39102YM is a great choice for these kinds of uses because it works well and converts power efficiently. It lets the power change smoothly, making sure that add-in cards work well in different PC systems.

● Voltage Conversion Scenarios

The MIC39102YM can help in certain voltage conversion situations, which are common in electrical systems. Some famous scenarios include:

● 5V to 3.3V Change

The regulator makes it possible to change a normal 5V supply to a lower 3.3V supply. This is often needed for interaction with 3.3V logic devices so that components can connect and talk to each other easily.

● 3.3V to 2.5V Conversion

In some situations, the voltage needs to go down even more, from 3.3V to 2.5V. The MIC39102YM makes this change easier and makes sure that components that work at 2.5 volts have the right voltage levels.

● 2.5V to 1.8V

Stepping down from 2.5V to 1.8V is another popular way to change the voltage. This is often needed to power sensitive parts or meet certain working needs. In this case, too, the MIC39102YM is a safe and efficient converter.

When you use the MIC39102YM in these voltage conversion situations, you get a reliable and stable power supply, efficient power conversion with minimal dropout voltage, and low ground current, which makes sure that components work well and last as long as possible.

Guaranteed Maximum Dropout Voltage: Ensuring Stability in Challenging Voltage Conditions

The MIC39102YM must have a specified maximum dropout voltage for stable operation, especially when the voltage conditions are difficult. It makes sure that power management is reliable and efficient by avoiding voltage drops that could affect components further down the line.

The MIC39102YM works well in the following voltage-change situations:

● Converting 5V to 3.3V

The regulator smoothly changes the 5V input voltage into a stable 3.3V output, so it can work with 3.3V logic devices.

● Converting 3.3V to 2.5V

By moving down from 3.3V to 2.5V in an efficient way, the regulator makes sure that 2.5V components get the most power with the least amount of dropout voltage.

● 2.5V to 1.8V Conversion

The regulator reliably lowers the voltage from 2.5V to 1.8V, making sure that 1.8V components get the best power source possible.

With its guaranteed maximum dropout voltage, the MIC39102YM keeps its stability and regulation even when the voltage conditions are difficult. This makes sure that the associated components always get consistent and reliable power.


By adding the MIC39102YM to your applications for power control, you can get the best performance and stability. Whether you’re making PC add-in cards or other systems that need to change voltage, the high performance of this regulator will take your projects to new heights.
