It has a wide range of applications, such as power management systems, power amplifiers, motor control, and battery monitoring systems.

Application Field

The LT1790ACS6-3.3#TRMPBF is designed for use in 3.3V systems, such as digital camera and PDA battery systems, generic microcontrollers and digital signal processors, and voltage feedback circuits. It is also suitable for use in low-noise, low cost power management and battery charging systems that require low noise, low quiescent current, and accurate voltage reference. Additionally, its high accuracy enables it to be used in power amplifiers, AC Motor Control, and other applications that require a precise level of voltage reference.

Working Principle

The LT1790ACS6-3.3#TRMPBF works by utilizing a bandgap reference which is then buffered with a Darlington current source to provide a low-noise, low-dropout voltage reference. This reference is then amplified with two metal-oxide semiconductor (MOS) transistor stages. The first stage acts as a voltage gain, while the second stage acts as a current gain. The output of the second stage is then connected to the bandgap reference, and the output is taken from the junction of the two MOS transistors. The result is a highly accurate and low noise voltage reference.
