TPS71750DSER is a low dropout (LDO) integrated linear voltage regulator manufactured Texas Instruments, specifically designed for communications and consumer applications. It is part of the broader family of PMIC (Power Management Integrated Circuit) voltage regulators. In particular, TPS71750DSE belong to the linear category, due to its familiar transistor configuration.

This voltage regulator’s field of applications is quite wide, from consumer systems as cellular phones or handheld terminals, to industrial broadcasts and broadcasting systems, as well as for pulsing power supplies. All of these electrical systems are usually powered by nominal 3.3 or 5.0V-Batteries, which can swing around +/- 5% on their output voltage, through the allowance of a low dropout voltage. TPS71750DSER was specifically made for those types of applications, given the advantages of space saving, low noise and confident usage.

The maximum input voltage of the TPS71750DSER is 6V, its fixed output voltage lies at 3.3V, 5.0V or adjustable, depending on the specific model, and its maximum output current of 1A remains efficient even in low dropout voltage, thanks to its high-speed-trans-conductance-amplifier-based design. Its output transistors are usually Heat Shrink Pack (HSP) or ceramic. When it comes to the quiescent current consumption, this part is as power-saving as possible. Throughout the nominal line, only 30µA is consumed, while in sleep mode, the current consumption falls back to 0.1µA.

Besides its tremendous low current consumption, the TPS71750DSER is extremely noise resistant which translates into better two-way communication in its field of application. It achieves this through a low-noise output filter, to guarantee stable current cleanness and avoid any overshoot in the voltage output. Last but not least, it has an internal soft start circuit (featured by a typical rise of 0.1µA/µs) that enhances its reliability in rapidly changing loads and avoids current over peaks.

When it comes to the device’s reliability, the TPS71750DSER shines above the competition with features such as short-circuit and Over-temperature protection, as well as the standard output over-voltage protection. All these elements combined make TPS71750DSER an irresistible offer for anyone in search of a valid voltage regulator option for their next project.
