UA78M10CKVURG3 Integrated Circuits (ICs)

The UA78M10CKVURG3 is a three-terminal adjustable regulator with excellent line and load regulation. Utilizing the ON Semiconductor BXB and BXC packages, this ultra-low-dropout (LDO) precision adjustable linear regulator is capable of supplying up to 1000mA output current over an output voltage range of 1.25V to 13.75V.

The UA78M10CKVURG3 is specifically designed for low-noise, high current dc applications and features extremely low output noise of 30µVRMS and an ultra-low dropout voltage of only 120mV @ 1000mA. This device also provides a very low ground current, making it ideal for battery-year applications.

The UA78M10CKVURG3 has good thermal characteristics and has a low power dissipation, making it suitable for use in a wide range of environmental conditions, including high temperature and low/high humidity. It is designed to operate over a wide input voltage range of 4.5V to 40V and is stable with any capacitor over 10µF.

Application Field and Working Principle

The UA78M10CKVURG3 is an ideal solution for applications in excellent line and load regulation, such as automotive, computer, instrumentation, telecommunication, low-noise and high-current DC applications. This LDO regulator is specifically designed to act as a precision adjustable linear regulator, allowing users to manipulate the output voltage of their system using a single device.

The device works by connecting to the power supply via its input terminal and provides a regulated output voltage using its feedback and control pin. When the output voltage at the output terminal exceeds the reference voltage set at the feedback pin, the output current is reduced until the output voltage at the output terminal is equal to the reference voltage set at the feedback pin. This maintains stability and accuracy of the output over an extensive range of input/output voltages and loads.

The UA78M10CKVURG3 is versatile, with user friendly features such as an internal current limit, thermal shutdown and over-voltage protection. Combined with its low noise, high output current and excellent thermal characteristics, the UA78M10CKVURG3 is the ideal choice for use in precision adjustable linear regulator applications.
