The TPS71715DCKR from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed for applications requiring a very low noise supply and high power supply rejection ratio (PSRR). This regulator is capable of delivering a continuous current of up to 150 mA while maintaining a low dropout voltage, making it an excellent choice for portable and battery-powered applications.

Key Features

• Output Voltage: The TPS71715DCKR provides a fixed output voltage of 1.5V, which is suitable for powering sensitive analog and digital circuits.
• High PSRR: With a PSRR of 70 dB at 1 kHz, this voltage regulator significantly reduces the impact of supply voltage fluctuations on the output voltage, thus delivering a stable and clean power supply.
• Low Dropout: The low dropout voltage allows the regulator to continue providing a regulated output even when the supply voltage is very close to the output voltage, enhancing efficiency in low-voltage operations.
• Low Quiescent Current: The TPS71715DCKR has a typical quiescent current of just 1 μA, making it ideal for battery-operated devices where power conservation is critical.
• Thermal Shutdown and Overcurrent Protection: Built-in safety features ensure the device operates within safe temperature and current limits, protecting both the regulator and the application from potential damage.
• Package: The device comes in a compact SC-70 package, which is highly suitable for space-constrained applications.
