ADM7155ACPZ-01-R7 - Ultra-Low Noise, High PSRR RF Linear Regulator

The ADM7155ACPZ-01-R7 from Analog Devices Inc. is a state-of-the-art linear voltage regulator designed specifically for noise-sensitive RF applications. This component boasts ultra-low noise performance and high power supply rejection ratio (PSRR), making it an ideal choice for maintaining signal integrity in high-frequency systems.

With an impressive low noise figure of only 1.0 µV RMS (10 Hz to 100 kHz), the ADM7155ACPZ-01-R7 ensures that the power supply does not introduce significant noise into sensitive RF circuits. This characteristic is particularly beneficial for applications such as PLLs, VCOs, high-speed data converters, and precision instrumentation where maintaining a clean power supply is crucial for optimal performance.

The device offers a PSRR of >70 dB up to 10 kHz, which means it can effectively suppress variations in the input power supply, thereby providing a stable output voltage. This is particularly important in environments where the input power supply may be subject to fluctuations or noise that could otherwise adversely affect the performance of the connected RF components.

With an input voltage range of 4.5 V to 16 V and an output voltage range of 1.5 V to 5.5 V, the ADM7155ACPZ-01-R7 is versatile and can be used in a wide array of applications. Its fixed output voltage of 1.0 V and output current capability of up to 600 mA make it suitable for powering a variety of low-voltage circuits.

The regulator is offered in a compact 8-lead LFCSP package, which not only saves board space but also provides excellent thermal performance. Additionally, the ADM7155ACPZ-01-R7 features over-temperature and over-current protection, enhancing the reliability and longevity of the device under various operating conditions.

Whether you are designing a high-precision analog front-end, a sensitive RF receiver, or any other application where power supply noise can be detrimental, the ADM7155ACPZ-01-R7 from Analog Devices Inc. provides a robust and high-performance solution.
