Analog Devices ADM7172ACPZ-2.5-R7 Ultra-Low Noise, High PSRR, RF Linear Regulator

The ADM7172ACPZ-2.5-R7 is a state-of-the-art linear voltage regulator manufactured by Analog Devices Inc., a company renowned for its high-performance analog, mixed-signal, and digital signal processing integrated circuits. This particular model is designed to deliver a fixed output voltage of 2.5V, with an impressive output current of up to 500 mA, making it an ideal choice for sensitive RF or analog circuitry that requires a clean power supply.

The ADM7172 boasts an ultra-low noise output, which is critical for maintaining signal integrity in high-performance applications. With a noise level of just 1.6 µV RMS over the 10 Hz to 100 kHz bandwidth, this regulator ensures that the power supply does not introduce significant noise into sensitive circuits. This feature is coupled with a high power supply rejection ratio (PSRR) of 70 dB at 10 kHz, which further contributes to its ability to provide a stable and clean voltage output, even in the presence of fluctuations in the input voltage.

Encased in a compact LFCSP (Lead Frame Chip Scale Package), the ADM7172ACPZ-2.5-R7 is designed for space-constrained applications. Its small footprint and low-profile package make it an excellent choice for portable devices, medical instruments, and other applications where size and weight are critical considerations.

Among the key features of this linear regulator is its wide input voltage range, from 4.5 V to 15 V, which provides flexibility in various system designs. Additionally, it offers thermal overload protection and short-circuit protection, which enhance the safety and reliability of the end application. The ADM7172 also has a low dropout voltage, ensuring efficient operation even when the input voltage is close to the output voltage.

With its combination of low noise, high PSRR, and robust protection features, the ADM7172ACPZ-2.5-R7 from Analog Devices Inc. is an excellent choice for designers looking to optimize the performance of their high-end and RF applications.
