MIC5235-5.0YM5 TR Series

series introduction

# Introduction to the MIC5235 - 5.0YM5 TR Product Series

## 1. Overview
The MIC5235 - 5.0YM5 TR is a part of a high - performance voltage regulator product series offered by Microchip Technology. Voltage regulators are essential components in electronic circuits, and this particular series is designed to provide stable and reliable power supply solutions for a wide range of applications.

## 2. Key Features

### 2.1 Output Voltage
The "5.0" in the product name indicates that the MIC5235 - 5.0YM5 TR is configured to provide a fixed output voltage of 5.0V. This precise output voltage is crucial for many electronic devices that require a specific power level to operate correctly. For example, in microcontroller - based systems, a stable 5V supply is often needed to power the microcontroller itself, as well as other peripheral components such as sensors and communication modules.

### 2.2 Low Dropout Voltage
One of the significant features of this product series is its low dropout voltage. Dropout voltage is the minimum difference between the input voltage and the output voltage required for the regulator to maintain a stable output. The MIC5235 - 5.0YM5 TR has a low dropout characteristic, which means it can operate efficiently even when the input voltage is only slightly higher than the output voltage. This is particularly useful in battery - powered applications, where the battery voltage gradually decreases over time. With a low dropout regulator, the system can continue to function properly for a longer period as the battery discharges.

### 2.3 Low Quiescent Current
Quiescent current refers to the current consumed by the regulator when there is no load connected. The MIC5235 - 5.0YM5 TR has a low quiescent current, which helps to conserve power in standby or low - power modes. In battery - operated devices, minimizing the quiescent current is essential to extend the battery life. For instance, in portable medical devices or wireless sensors that spend most of their time in a low - power state, the low quiescent current of this regulator can significantly reduce the overall power consumption.

### 2.4 Thermal Shutdown and Current Limiting
To ensure the safety and reliability of the regulator and the connected circuits, the MIC5235 - 5.0YM5 TR is equipped with thermal shutdown and current - limiting features. Thermal shutdown protects the device from overheating by automatically shutting down the regulator when the temperature exceeds a certain threshold. Current limiting, on the other hand, prevents excessive current from flowing through the regulator, which could damage the device or other components in the circuit. These protection mechanisms enhance the robustness of the product and make it suitable for use in various harsh environments.

## 3. Package and Pin Configuration
The "YM5" in the product name refers to the package type. The MIC5235 - 5.0YM5 TR comes in a small - sized surface - mount package, which is ideal for applications where space is limited. The compact package allows for easy integration into printed circuit boards (PCBs), especially in portable and miniaturized electronic devices.

The pin configuration of the MIC5235 - 5.0YM5 TR is designed for straightforward connection. It typically has pins for input voltage, output voltage, ground, and in some cases, additional pins for enable or adjustment functions. The clear pin layout simplifies the PCB design process and reduces the chances of connection errors.

## 4. Applications

### 4.1 Consumer Electronics
In consumer electronics such as smartphones, tablets, and portable media players, the MIC5235 - 5.0YM5 TR can be used to provide a stable 5V power supply for various components. For
