Introduction

The LM1086CSX-2.85/NOPB is a voltage regulator of the Linear PMIC (Power Management Integrated Circuit) series. The LM1086CSX-2.85/NOPB is designed to provide high current, low noise, and high performance voltage regulation. It is also designed to be a drop-in replacement for the popular 78xx series of linear regulators.

Features

The LM1086CSX-2.85/NOPB offers many useful features for voltage regulation. It has a wide 2.5V to 28V input voltage range that allows it to be used in many different applications. It also has a wide output range from 1.25V to 27V, and is capable of providing up to 2A of output current. It also features Output Adjust, Shutdown, and Over Temperature Protection (OTP) features. Finally, it is RoHS (Restriction of Hazardous Substances) compliant and is lead-free, making it an environmentally friendly option.

Applications

The LM1086CSX-2.85/NOPB is suitable for a wide range of applications. It can be used in 12V to 6V and 24V to 12V DC/DC converters, battery-powered systems, power supply circuits, computers, and communications devices, as well as other DC powered devices. It can also be used in automotive, industrial, and medical applications.

Working Principle

The LM1086CSX-2.85/NOPB utilizes a passive 2-terminal voltage divider network to control the output voltage of the regulator. This voltage divider network is designed to reduce the input voltage down to the desired output voltage based on the values of the resistors. The voltage divider is then connected to the enable pin of the regulator. When the enable pin is pulled high, the regulator turns on and supplies regulated output voltage. The LM1086CSX-2.85/NOPB also features Output Adjust, Shutdown, and Over Temperature Protection (OTP) features to increase the stability and reliability of the power supply. The Output Adjust features allow the output voltage to be adjusted to the desired level via a resistor divider network. The Shutdown feature allows the regulator to be shut off, reducing power consumption and increasing efficiency. Finally, the OTP feature prevents the regulator from exceeding its temperature limit.

Conclusion

The LM1086CSX-2.85/NOPB is an excellent choice for voltage regulation applications. It offers excellent performance and is RoHS compliant. Its wide 2.5V to 28V input voltage range and 1.25V to 27V output voltage range make it suitable for a variety of applications. The Output Adjust, Shutdown, and Over Temperature Protection features provide increased stability and reliability.
