**LT1964ES5-BYP#TRMPBF: A 200mA Low-Noise LDO Voltage Regulator in SOT-23 Package**

In the world of power management, the demand for compact, efficient, and clean voltage regulation is paramount, especially in space-constrained and noise-sensitive applications. The **LT1964ES5-BYP#TRMPBF** from Analog Devices stands out as a premier solution, **integrating a 200mA low-dropout (LDO) regulator into a tiny SOT-23-5 package**. This combination of high performance and minimal footprint makes it an ideal choice for modern portable electronics, RF and precision analog circuits, and battery-powered devices.

The core strength of this regulator lies in its **exceptionally low output noise performance**, which is critical for powering sensitive components like VCOs (Voltage-Controlled Oscillators), ADCs (Analog-to-Digital Converters), and DACs (Digital-to-Analog Converters). By utilizing the dedicated **BYP (Bypass) pin** with an external capacitor, the internal reference noise can be drastically reduced to levels as low as **20μVRMS over a 10Hz to 100kHz bandwidth**. This feature ensures that the regulator itself does not introduce noise that could degrade the signal integrity of the system it powers.

Furthermore, the LT1964ES5-BYP exhibits a **low dropout voltage of typically 300mV at full 200mA load**, maximizing efficiency and extending battery life in portable applications. Its wide input voltage range, from 2.85V to 20V, provides significant design flexibility. The device also incorporates essential protection features such as **current limiting and thermal shutdown**, safeguarding both the regulator and the load under fault conditions. The stable operation with low-ESR ceramic capacitors simplifies design and reduces the overall bill of materials cost.

**ICGOODFIND**: The LT1964ES5-BYP#TRMPBF is a superior component for designers who must reconcile the conflicting demands of high performance, minimal board space, and low noise. Its specialized bypass pin for ultra-low noise, robust protection features, and stable operation with modern capacitors position it as a top-tier choice for powering the most sensitive circuits in a compact form factor.
