Application Field
The LT3507AEFE#TRPBF is suitable for a variety of applications requiring a low dropout linear regulator. It is ideal for embedded systems that require precise control of the output voltage, such as portable devices and cellular phones. It is also suitable for portable medical equipment and industrial applications that require very low quiescent current.
Working Principle
The LT3507AEFE#TRPBF operates by comparing the reference voltage at the ADJ terminal with a feedback voltage derived from the output voltage. The error voltage at the COMP pin is then used to adjust the output voltage. In addition, the load and line regulation of the regulator depends on the IADJ current and the feedback resistors to determine the ADJ pin voltage. If the output voltage drops or increases, the voltage at the ADJ pin is also adjusted accordingly. The LT3507AEFE#TRPBF also features a built-in thermal shutdown feature, which provides protection against excessive output currents and excessive thermal conditions.
Conclusion
The LT3507AEFE#TRPBF is a high-performance low dropout linear regulator offering the performance and small size required for the most demanding power supply applications. It is suitable for a wide range of low power applications requiring tight line and load regulation and long service life under varying operating conditions. It features excellent line and load regulation and very low quiescent current, as well as integrated thermal shutdown circuitry for added protection.
