TPS7A8701RTJT

The TPS7A8701RTJT is a high-performance, low-power linear voltage regulator from Texas Instruments’ TPS7A8x01 family. It delivers a low noise, low dropout, low quiescent current regulator in a tiny 2 mm x 1.4 mm footprint. It is ideal for portable and handheld products and applications that require ultra-low power dissipation and high output accuracy. This voltage regulator can deliver up to a maximum of 1000 mA of output current, with adjustable output voltage from 0.8 V to 10 V, and fixed 0.5 V output voltage tolerance.

The TPS7A8701RTJT’s operating temperature range is -40°C to 125°C, making it suitable for a wide range of high-temperature applications. It also offers high operating stability, with an operating temperature drift of less than 0.1 mV/°C. The TPS7A8701RTJT is designed to provide a power solution for 200 mA or higher load applications, such as digital potentiometers, sensor boards and power management ICs. It is also suitable for powering high-speed digital devices, which demand extremely low-noise power supply rails.

Application Field

The TPS7A8701RTJT features a small footprint and low noise, making it ideal for applications such as cell phones and other handheld devices, where size, weight, and power consumption are critical considerations. It is also suitable for wireless modems and home networking equipment, as well as medical instruments, GPS receivers, set-top boxes, MP3 players, and automotive electronics.

Working Principle

The TPS7A8701RTJT is a low-noise, low-dropout linear regulator that uses an advanced control loop mechanism for regulating the output voltage. It uses an internal pass device to regulate the voltage output, allowing for a very low dropout voltage across the regulator and a wide range of output current. The TPS7A8701RTJT also features an innovative constant-voltage/constant-current protection circuit that eliminates the need for an external current limit circuit. It also has a built-in thermal shutdown protection circuit to prevent damage if the internal temperature rises too high. The TPS7A8701RTJT is designed for applications where the load current varies significantly and requires an output voltage that is accurate and stable over a wide range of temperatures.
