Introduction

The TC1263-3.0VETTR is a multifunctional, integrated circuit voltage regulator designed for use in many applications, ranging from general purpose signal conditioning to automotive, aerospace and industrial applications. With its high-efficiency, low-noise performance, this product offers users greater flexibility and reliability in many applications.

Description

The TC1263-3.0VETTR is an ultra low noise linear voltage regulator with a high power density, capable of delivering up to 3.0A of peak output current. It integrates a low drop-out linear regulator, switching control logic and thermal protection circuitry into a single package, allowing for an efficient and cost-effective solution. Using internal compensation, the device is design optimized for fast transient response and excellent line, load and temperature tracking. Its low-noise design providse an output voltage ripple of 1 mVrms (20 MHz bandwidth). Externally provided resistors are used to set the output voltage, with a voltage range of 1 V to 10 V (25 mV Steps), while the voltage can be adjusted to a +/-2.5% accuracy.The TC1263-3.0VETTR also features an enable pin, to allow for the powering-down of the device. Additional features include reverse voltage protection, thermal shutdown, overcurrent protection, output voltage tracking and monitoring, and protection againest over-temperature (OTP) operation.

Application Field and Working Principle

The TC1263-3.0VETTR is suitable for a wide range of applications such as medical and consumer systems, automotive, industrial, LEDs and advanced illumination systems, battery-powered devices and consumer lighting.The device works by providing a regulated output voltage, by taking the input voltage and comparing it to the regulated voltage set by external resistors connected to the "Vout" terminal. If the input voltage is higher than the regulated output, the device will reduce the input voltage by the difference. Conversely, if the input voltage is lower than the regulated output, the device will increase the input voltage by the difference. This process is repeated continuously with the internal circuitry of the TC1263-3.0VETTR controlling the process for efficient, low-noise power delivery.

Conclusion

The TC1263-3.0VETTR is a highly efficient, low-noise, low-drop-out linear voltage regulator capable of delivering up to 3.0A of current. With its fast transient response, adjustable output voltage and protection features, it is suitable for a wide range of applications from general purpose signal conditioning to automotive, aerospace, and industrial applications.
