SIP21106DR-26-E3 Application Field and Working Principle

SIP21106DR-26-E3 is a class of linear voltage regulators that is manufactured by STMicroelectronics, a leading provider of innovative power management solutions. The SIP21106DR-26-E3 is an advanced solution for intelligent and precise voltage regulation with low-dropout operation. This voltage regulator is designed to regulate voltage from an input source of up to 32V down to an output of up to 24V while allowing up to 6A of output current. It is also capable of handling fast transient load changes and operating at a wide operational temperature range. This makes it an ideal solution for a wide variety of applications that require precise regulation of input voltage.

Application Field

The versatile nature of the SIP21106DR-26-E3 has made it the voltage regulator of choice for a wide array of applications, including portable and automotive systems, LED lighting, industrial and process control, and measurement and communication systems. This wide range of applications is possible due to the range of features this regulator has to offer. It features high efficiency, low dropout operation, wide operational temperature range, low noise operation, and high output ripple rejection. Additionally, the SIP21106DR-26-E3 is designed to be easy to use and can be set up with only a few external components.

Working Principle

The SIP21106DR-26-E3 works by using a sensing element which regulates the output voltage by modulating the output current. This sensing element is controlled using a voltage-reference and an error amplifier. When the output voltage is above the setpoint, the error amplifier drives the sense element more off, reducing the output voltage. Conversely, when the output voltage is lower than the setpoint, the sense element is driven more on, increasing the output voltage. This modulation of the output current is how the SIP21106DR-26-E3 is able to precisely regulate the output voltage.

In addition to controlling the output current, the SIP21106DR-26-E3 also has several other features to ensure reliable and safe operation. These include short-circuit protection, thermal shutdown, and over-voltage protection. The short-circuit protection prevents the output current from exceeding the specified limit and will disable the regulator if the set limit is surpassed. The thermal shutdown feature ensures that the regulator does not overheat and will shut off the regulator once the operating temperature reaches a certain point. Finally, the over-voltage protection prevents the output voltage from reaching a dangerous level and can be set to any level from 4.5V up to 32V.

Conclusion

In conclusion, the SIP21106DR-26-E3 is an advanced linear voltage regulator that offers a wide range of features to meet the needs of a variety of applications. It has a wide operational temperature range and can handle fast transient load changes along with low-dropout operation. Additionally, it has several additional safety features to protect the regulator and its output. Thanks to its range of features and capabilities, the SIP21106DR-26-E3 is a leading choice for portable and automotive systems, LED lighting, industrial and process control, and measurement and communication systems.
