Product Overview: TPS79628DRBT

The TPS79628DRBT is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a stable and precise output voltage. This particular model is part of TI's TPS796xx series, which is renowned for providing ultra-low noise, high power supply rejection ratio (PSRR), and low quiescent current, making it an ideal choice for sensitive RF and analog circuitry that require a clean power supply.

This LDO regulator offers a fixed output voltage of 2.8V, with an impressive dropout voltage of just 85mV at a 1A load. This feature allows for efficient operation even when the supply voltage is very close to the output voltage, which is beneficial in battery-operated devices where maximizing the usage of the available voltage is crucial.

The TPS79628DRBT comes in a compact 3x3 SON-8 package, which is suitable for space-constrained applications. It is capable of delivering up to 1A of continuous output current, ensuring a reliable power supply for a wide range of applications. Additionally, the device includes thermal shutdown and current limit features to protect against overcurrent and overheating conditions.

One of the key features of the TPS79628DRBT is its low noise performance, with a typical output noise of only 34µVRMS over a 10Hz to 100kHz bandwidth. This characteristic, combined with a high PSRR of 70dB at 1kHz, makes it an excellent choice for powering noise-sensitive components such as precision ADCs, DACs, and audio ICs.

The device also offers a fast transient response, which helps maintain a stable output voltage despite rapid changes in load, ensuring consistent performance for dynamic applications. Moreover, the TPS79628DRBT includes an enable pin, allowing the regulator to be switched on or off, providing additional power management flexibility.

Overall, the TPS79628DRBT from Texas Instruments is a versatile LDO voltage regulator that provides high accuracy, low noise, and robust protection features. It is a perfect solution for applications that demand a clean and stable power supply, such as portable devices, wireless communication equipment, and medical electronics.
