It is used in applications requiring lower current requirement, higher noise immunity, and low power consumption. It can be used in many different application fields, such as cellular/mobile phone, LED lighting, automotive application, printer, hand-held device, computer peripherals, wireless application, and audio-visual equipment.

Working Principle

The CAT8900B180TBGT3 is an operational amplifier with a fixed voltage reference. The fixed voltage reference is set by a transistor in the IC and can not be changed. When an input voltage is applied to the terminals, it is compared with the fixed voltage reference. If the voltage sensed at the terminals is below the fixed voltage reference, the transistor triggers and increases the output of the operational amplifier. The operational amplifier also regulates output current to protect the IC from being damaged due to excessive input current. The output current is then passed through a power conversion convertor which then converts it to the correct voltage level.

In addition, the CAT8900B180TBGT3 IC also incorporates several other features such as thermal management, over-voltage protection, and surge current protection. These features help the IC to be more resilient against temperature fluctuations and out of spec input voltages, prolonging its life and increasing its reliability.
