The linear voltage regulation and simple design of the S-1137D33-U5T1U make it an ideal part for a variety of applications in which accurate voltage regulation is required.

Application Field

The S-1137D33-U5T1U is perfect for applications that require a 3.3V output voltage with low noise, stability and accuracy, such as powering microprocessors and DSPs, and providing efficient USB power in mobile and laptop computers. It is also frequently used in automotive systems, telecommunication base stations and PDAs.

The device’s wide input voltage range, high 3A output current, low voltage dropout and tight line and load regulation make it suitable for many battery-powered applications, as well as inregulated benchtop power supplies that are used to power a variety of test equipment, soldering tools and other devices.

Working Principle

The S-1137D33-U5T1U was designed to provide a reliable 3.3V output voltage over a wide input voltage range. The device works by using a PNP pass element, a voltage reference and some other peripheral circuitry to reduce the input voltage to the optimal level for powering the load. The internal voltage reference provides the exact 3.3V that is required for the load, and the PNP pass element serves to reduce the input voltage to the desired level. The device also includes internal protection features such as over-current protection, under-voltage lockout, over-temperature protection, and over-voltage protection, to protect against any liabilities caused by an unregulated output due to an interruption or excess input voltage.

The S-1137D33-U5T1U also has a wide range of input “on” and “off” threshold voltages, allowing it to be used in many different applications. Furthermore, the device can also be used for applications with lower voltage, such as 2.5V, through the use of internal “force off-circuit” control.

Overall, the S-1137D33-U5T1U is an ideal device for efficient, reliable and accurate voltage regulation. Its wide input voltage range, high output current, low dropout voltage, tight line and load regulation, and a variety of protection features make it the perfect part for many different applications.
