TPS7A4701QRGWRQ1

TPS7A4701QRGWRQ1 is an ultra-low soluble voltage regulator with an output voltage range of 1.2 V to 6 V. It typically delivers up to 10 mA of steady, low-dropout output current and is ideal for applications where transients and noise must be minimized. This ultra-low noise performance is achieved through the use of high-performance voltage regulator power supply.

The on-chip low dropout regulator provides tight regulation for improved transient and noise performance over standard linear solutions, while the active control of the output voltage further improves total dropout voltage and output voltage accuracy from part to part. In addition, the regulatory power supply design ensures a tight output voltage variance under multiple loading conditions.

The TPS7A4701QRGWRQ1 is designed for applications where low power consumption and high noise immunity are critical. Examples of such applications include processor core regulators, RF power amplifiers, voltage level shifters, medical devices, power bus converters, automotive controllers, and other designs where high transient regulation performance is needed. The device features internal thermal shutdown and short circuit protection to ensure safe operation in the event of device overload.

The TPS7A4701QRGWRQ1 is a low power linear regulator with a remarkably low supply current of just 7 μA. The ultra-low-noise operation is further improved by the use of low noise reference and package, which help minimize output noise. The TPS7A4701QRGWRQ1 is capable of providing either a positive output voltage or a negative output voltage, depending on the logic levels supplied to the pins. All necessary components are included to generate the bias voltage required for the regulator to operate correctly.

In terms of working principle, the TPS7A4701QRGWRQ1 contains an internal error amplifier, two comparators, a slew rate limited drive transistor, and a foldback protection circuit. At startup, the voltage at the output is monitored by the comparators and the reference voltage is compared with the desired output voltage. If the output voltage is higher than the reference voltage, the internal error amplifier pulls the drive transistor low and decreases the output voltage. On the other hand, if the output voltage is lower than the reference voltage, the internal error amplifier increases the drive transistor\'s output which increases the output voltage. This voltage regulation loop keeps the output voltage at the desired constant value regardless of operating conditions.

In summary, the TPS7A4701QRGWRQ1 is an ultra-low dropout linear voltage regulator for applications where low noise and high transient performance are needed. It features low power consumption, fast transient response, low output noise, and a wide output voltage range. It is ideal for processor core regulators, RF power amplifiers, voltage level shifters, medical devices, power bus converters, automotive controllers, and other designs requiring high transient regulation performance.
