series introduction

# LT1086IT - 12 Product Series Introduction

## 1. Overview
The LT1086IT - 12 belongs to a high - performance linear voltage regulator product series. Linear voltage regulators are crucial components in electronic circuits, responsible for converting an unregulated input voltage into a stable and precise output voltage. The LT1086IT - 12 is specifically designed to provide a fixed output voltage of 12V, making it suitable for a wide range of applications where a reliable 12V power supply is required.

## 2. Key Features

### 2.1 High Output Current Capability
One of the standout features of the LT1086IT - 12 is its ability to deliver a relatively high output current. It can typically supply up to 5A of continuous output current, which makes it suitable for powering power - hungry components such as microprocessors, high - power amplifiers, and other electronic devices that demand a significant amount of current.

### 2.2 Low Dropout Voltage
The dropout voltage of the LT1086IT - 12 is relatively low. Dropout voltage is the minimum difference between the input voltage and the output voltage required for the regulator to maintain a stable output. A low dropout voltage means that the regulator can operate efficiently even when the input voltage is only slightly higher than the output voltage. For the LT1086IT - 12, this allows for more flexibility in power supply design and can help reduce power dissipation, especially in battery - powered applications.

### 2.3 Excellent Line and Load Regulation
Line regulation refers to the ability of the regulator to maintain a constant output voltage when the input voltage changes. Load regulation, on the other hand, is the regulator's ability to keep the output voltage stable as the load current varies. The LT1086IT - 12 offers excellent line and load regulation characteristics. This ensures that the output voltage remains within a tight tolerance, even in the face of fluctuations in the input voltage or changes in the load current. As a result, the connected electronic devices can operate more reliably.

### 2.4 Thermal Protection
To prevent damage due to overheating, the LT1086IT - 12 is equipped with built - in thermal protection. When the temperature of the regulator exceeds a certain threshold, the thermal protection circuit will automatically reduce the output current or shut down the regulator to prevent it from overheating. This feature enhances the reliability and longevity of the regulator, especially in high - power applications where heat generation is a concern.

### 2.5 Adjustable Output (with additional components)
Although the LT1086IT - 12 is a fixed 12V output regulator, with the addition of a few external components, it can be configured to provide an adjustable output voltage. This flexibility allows designers to adapt the regulator to different application requirements, expanding its range of use cases.

## 3. Package and Pinout
The LT1086IT - 12 is typically available in a TO - 220 package. The TO - 220 package is a widely used through - hole package that offers good thermal performance and mechanical stability. It is easy to mount on printed circuit boards (PCBs) and can be effectively cooled using heat sinks if necessary.

The pinout of the LT1086IT - 12 is designed for easy integration into electronic circuits. It has three main pins: the input pin (VIN), the output pin (VOUT), and the adjust pin (ADJ). The input pin is connected to the unregulated input voltage source, the output pin provides the regulated 12V output voltage, and the adjust pin can be used for additional functions such as adjusting the output voltage when configured in an
