**The ADP7183ACPZN5-R7: A High-Performance, Negative Voltage LDO Linear Regulator**

In the world of power management, where system noise, thermal performance, and board space are paramount, **low-dropout linear regulators (LDOs)** remain a critical component for providing clean, stable power to noise-sensitive circuits. For applications requiring a negative supply rail, such as precision operational amplifiers, data converters, and RF components, the **ADP7183ACPZN5-R7** stands out as a premier solution, engineered to deliver exceptional performance where it matters most.

**Uncompromising Performance and Precision**

The ADP7183ACPZN5-R7 is designed to convert a negative input voltage as low as -3.5V to a precisely regulated output adjustable down to -2.0V, with a fixed -5.0V option also available. Its key strength lies in its ability to maintain **excellent line and load regulation** with a maximum dropout voltage of just 240 mV at a 300 mA load. This high current capability, combined with a low dropout voltage, makes it exceptionally efficient for linear regulation, minimizing power loss and heat generation in a compact form factor.

A defining characteristic of this LDO is its **ultra-low noise performance of 6.5 μV√Hz** and outstanding **power supply rejection ratio (PSRR) of 70 dB at 10 kHz**. This exceptional noise performance ensures that even the most sensitive analog components are shielded from power supply disturbances, a critical requirement for maintaining signal integrity in high-precision audio, medical instrumentation, and communication systems.

**Robustness and Integration for Demanding Applications**

Beyond its core regulation function, the ADP7183ACPZN5-R7 is built for reliability. It features internal current limiting and thermal overload protection, safeguarding both the regulator and the load under fault conditions. The device operates over a wide junction temperature range of -40°C to +125°C, making it suitable for industrial and automotive environments.

Housed in a space-saving, 8-lead **3 mm × 3 mm LFCSP package**, it offers an optimal balance of thermal performance and minimal PCB area. The enable pin provides simple on/off control, facilitating power sequencing and helping to reduce overall system power consumption in battery-operated devices.
