**ADP1752ACPZ-2-R7: A Compact, High-Performance 2V Linear Regulator for Noise-Sensitive Applications**

In the realm of modern electronics, managing power efficiently while minimizing noise is a critical challenge, especially for sensitive analog and RF circuits. The **ADP1752ACPZ-2-R7** from Analog Devices stands out as a premier solution, engineered to deliver **exceptional power supply rejection and ultra-low noise** in a compact form factor. This 2V fixed-output linear regulator is designed to meet the stringent requirements of applications where even the slightest power fluctuation can degrade performance.

**Key Features and Advantages**

The ADP1752ACPZ-2-R7 integrates advanced design techniques to achieve remarkable performance metrics. It offers a **high power supply rejection ratio (PSRR)** of up to 75 dB at 10 kHz, effectively blocking unwanted noise from upstream switching regulators or other noisy power sources. This makes it ideal for powering **noise-sensitive components** such as precision sensors, RF transceivers, PLLs/VCOs, and high-resolution data converters (ADCs/DACs). With an ultra-low output noise of just 9 μV RMS (typical), it ensures that the power supply does not introduce errors or interfere with signal integrity.

Despite its high performance, the device is housed in a tiny **2 mm × 2 mm LFCSP package**, making it suitable for space-constrained PCB designs. It supports a wide input voltage range from 2.3 V to 5.5 V and provides a fixed 2.0 V output with a maximum output current of 500 mA. The regulator also incorporates **protection features** like current limiting and thermal shutdown, enhancing system reliability under fault conditions.

**Application Scenarios**

The ADP1752ACPZ-2-R7 excels in applications where clean power is non-negotiable. In **medical imaging equipment**, such as ultrasound machines, it powers analog front-ends to ensure accurate signal acquisition. For **wireless communication systems**, it provides stable voltage to RF modules, minimizing phase noise and improving signal clarity. Additionally, in **test and measurement instruments**, it helps maintain precision by reducing power-induced artifacts.

**ICGOODFIND**: The ADP1752ACPZ-2-R7 is a top-tier linear regulator that combines **miniaturization, high PSRR, and ultra-low noise** in a single package. It addresses the critical need for clean power in advanced electronic systems, offering designers a reliable and efficient solution for noise-sensitive applications.
