UA7810CKC

Introduction

The UA7810CKC is a Linear Voltage Regulator, part of the more general class of Power Management IC\'s (PMIC). It provides cost-effective and high-performance voltage regulation and power control solutions. As a linear voltage regulator, it offers the advantage of low component count and minimal component stresses, offering a stable supply for a wide range of applications. This article outlines the application fields and working principle of UA7810CKC.

Application Fields

The UA7810CKC can be used as a general-purpose voltage regulator in a variety of applications, including:

• Home Appliances
• Automotive Systems
• Industrial Equipment
• Telecommunications Systems
• Portable Devices

It offers high efficiency and low noise. Specifically, it can be used in welding machines, electric motors, and UPS systems. In addition, UA7810CKC is suitable for use in high-speed systems as its switching frequency is 101 KHz.

Technical Specifications

The UA7810CKC offers adjustable or fixed output voltage in the range of 1.235V to 37V and offers up to 2A of current. It has a wide input voltage range of 4.5V to 40V and operates in the temperature range of 0°C to +125°C. It is available in 3.5mm X 3.5mm QFN-16 package for easy integration into the electronics system. The UA7810CKC offers integrated under voltage lockout protection, over temperature shutdown, and over current protection. It also features an enable pin that can be used to shut down the regulator if necessary.

Working Principle

The UA7810CKC is an adjustable output voltage regulator that uses an internal voltage reference (VREF) and an error amplifier to regulate the output voltage. The integrated error amplifier compares the output voltage with the internal voltage reference (VREF) and adjusts the output voltage till the two levels match. The output current is limited by an internal current limiter, which switches off the regulator under heavy or short-circuit load conditions. This ensures safe operation of the regulator and the electronic system it is protecting.

The UA7810CKC also features an enable pin that can be used to shut down the regulator. This can be used to reduce the voltage directly without having to cycle the power or having to reset the IC. This feature makes the UA7810CKC suitable for use in portable devices where power conservation is important.

In summary, the UA7810CKC is a high-performance, cost-effective linear voltage regulator with a wide range of applications in home appliances, telecommunications systems, industrial equipment, automotive systems and portable devices. Its integrated features, such as under voltage lockout protection and thermal shutdown, make it an ideal choice for a variety of applications.
