PMIC - Voltage Regulators - Linear: LT1121HVIS8#PBF Application Field and Working Principle.

The LT1121HVIS-8#PBF is a high-current, low-dropout, adjustable linear regulator for both DC-DC and AC-DC applications. The regulator’s output voltage can be adjusted from 1.2V to 134V, and its drop-out voltage is typically 0.9V at full load. It is designed to deliver up to 25A of continuous output current to any drop-out voltage and up to 250mA at full adjustment range. The LT1121HVIS-8#PBF also offers a wide input voltage range of up to 40V, and can operate from a single supply of up to 40V. Its very low noise performance ensures it can be used in high performance systems.

The LT1121HVIS-8#PBF linear regulator is most commonly used in DC-DC and AC-DC applications such as automotive, motor control, factory automation, process control, and lighting applications. It delivers very low noise performance, which is useful in high performance systems. It also has EMI filtering protection and reverse current blocking, making it ideal for applications where these features are required.

The LT1121HVIS-8#PBF has three main components in its design: the input filter, the reference divider, and the feedback and error amplifier. The input filter removes high-frequency noise and allows the regulator to work faster and with greater accuracy. The reference divider converts the input voltage into a reference voltage, while the feedback and error amplifier compares the reference voltage to the output voltage and makes necessary adjustments to the output voltage to maintain the required level.

The LT1121HVIS-8#PBF linear regulator offers several built-in protection features to ensure safety and reliability. It has an over-current protection feature which shuts down the output when the current exceeds a certain level. It also has thermal shutdown protection which protects the circuit when the temperature exceeds a certain limit. The over-voltage protection feature prevents the output voltage from exceeding a specified level by resetting the output. The under-voltage protection feature also prevents the output voltage from falling below a minimum level by resetting the output.

Overall, the LT1121HVIS-8#PBF is a robust, high-performance, adjustable linear regulator for both DC-DC and AC-DC applications. With its wide input voltage range of up to 40V, and its very low drop-out voltage of 0.9V at full load, it is an ideal choice for those looking for a reliable and efficient power solution. Its built-in protection features further increase its reliability and overall performance. The LT1121HVIS-8#PBF linear regulator is an ideal device for high performance applications that require superior performance and reliability.
