**LT1761IS5-2#TRMPBF: A 2V, 100mA Low-Noise LDO Regulator in SOT-23 Package**

In the world of power management, the demand for compact, efficient, and clean voltage regulation is ever-increasing. The **LT1761IS5-2#TRMPBF** from Analog Devices stands out as a premier solution, specifically engineered to meet these critical needs. This monolithic, low-dropout (LDO) regulator is designed to deliver a fixed **2V output at up to 100mA** of current, making it an ideal choice for a wide array of portable and noise-sensitive applications.

Housed in a minuscule **SOT-23 package**, this regulator is a perfect fit for space-constrained PCB designs, such as those found in handheld medical devices, IoT sensors, and portable audio equipment. Despite its small footprint, it does not compromise on performance. A key feature of the LT1761IS5-2 is its **exceptionally low output noise**, typically measuring just 20μVRMS over a 10Hz to 100kHz bandwidth. This is paramount for powering sensitive analog circuitry, RF modules, and precision data converters where even minor power supply fluctuations can degrade overall system performance.

Furthermore, the device exhibits an impressively **low dropout voltage** of merely 300mV at full 100mA load. This high efficiency ensures stable operation even as the input voltage approaches the output level, thereby extending battery life in portable systems. The regulator is also designed for stability with tiny, low-ESR ceramic capacitors, simplifying the bill of materials and reducing overall solution size. Additional built-in protections, including current limiting and thermal shutdown, safeguard both the IC and the load under fault conditions.

**ICGOOODFIND**: The LT1761IS5-2#TRMPBF is a quintessential component for designers seeking a reliable, high-performance, and space-efficient power management solution. Its combination of ultra-low noise, low dropout voltage, and robust protection features in a SOT-23 package makes it an outstanding choice for powering the next generation of portable and precision electronic devices.
