**LT3060EDC-3#TRPBF: A 3V, 200mA Low-Noise LDO Regulator in a 2mm x 2mm DFN Package**

In the world of power management, the demand for compact, efficient, and low-noise voltage regulation continues to grow, especially in space-constrained and noise-sensitive applications. The **LT3060EDC-3#TRPBF** from Analog Devices stands out as a premier solution, delivering a fixed **3V output** at up to **200mA** of continuous current with exceptional performance. Housed in an ultra-small **2mm x 2mm DFN package**, this low-dropout (LDO) regulator is engineered for modern portable electronics, medical devices, and precision instrumentation where board space and clean power are at a premium.

**Key Features and Performance Advantages**

The core strength of the LT3060EDC-3#TRPBF lies in its remarkably **low output noise**—typically just **30µVRMS** over a 10Hz to 100kHz bandwidth. This is achieved without the need for any external bypass capacitors on the reference pin, simplifying design and saving additional board space. For applications requiring even lower noise, an optional external bypass capacitor can further reduce noise to as low as **20µVRMS**. Furthermore, it features an impressively **low dropout voltage** of only **160mV** at full 200mA load, maximizing efficiency and extending battery life in portable devices.

The device incorporates a wide input voltage range from **1.6V to 20V**, providing significant flexibility for systems powered by multiple sources, including multi-cell batteries or unregulated wall adapters. Its high **PSRR (Power Supply Rejection Ratio)** of **76dB** at 1kHz effectively filters input ripple, ensuring a stable and clean output even in the presence of a noisy input supply.

**Robustness and Integration**

Beyond its primary regulation function, the LT3060EDC is built for reliability. It includes built-in protection features such as **current limit** and **thermal shutdown**, safeguarding both the regulator and the downstream circuitry under fault conditions. The stable operation is maintained with a very small, low-ESR ceramic output capacitor of just **2.2µF**, which is essential for minimizing the total solution size.

The **2mm x 2mm DFN (Dual Flat No-Lead) package** is a critical enabler for miniaturization. With its compact footprint and low profile, it is ideally suited for high-density PCB designs found in wearables, IoT modules, and other advanced portable gadgets.

**ICGOODFIND**: The LT3060EDC-3#TRPBF is a superior choice for designers who need a high-performance, miniature LDO. It masterfully combines **ultra-low noise**, a **high current capability** of 200mA, and **outstanding PSRR** in one of the smallest available packages, making it an indispensable component for powering sensitive analog circuits.
