LT1761IS5-2.5#TRPBF - Low Noise, Low Dropout Voltage Regulator

The LT1761IS5-2.5#TRPBF is a high-performance, low dropout voltage regulator from Linear Technology, designed to deliver a well-regulated 2.5V output. This regulator is part of the LT1761 series, known for its low noise operations and excellent power supply rejection ratio (PSRR), making it an ideal choice for sensitive RF and analog circuitry that requires a clean power source.

With its ability to deliver up to 100mA of output current, this device maintains a low dropout voltage of just 300mV at full load, ensuring efficient operation even when the input voltage is close to the output voltage. This feature is particularly beneficial in battery-powered applications where maximizing the usage of available power is crucial.

The LT1761IS5-2.5#TRPBF stands out for its low quiescent current, which is typically only 20µA, making it an excellent choice for portable and battery-powered devices where power conservation is key. Additionally, the shutdown current is a mere 0.1µA, further enhancing its power-saving capabilities.

One of the notable features of this voltage regulator is its ability to suppress noise without the need for an additional noise bypass capacitor, although adding a 10nF bypass capacitor can further reduce output noise to a remarkably low 20µV RMS. This makes the LT1761 series particularly suitable for noise-sensitive applications such as precision instrumentation, data acquisition systems, and high-end audio equipment.

The device is offered in a compact SOT-23 package, which is ideal for space-constrained applications. The LT1761IS5-2.5#TRPBF also includes several protective features, such as overcurrent and overtemperature protection, ensuring reliable operation under various conditions.

Overall, the LT1761IS5-2.5#TRPBF from Linear Technology is a robust and reliable choice for designers looking to maintain a stable and clean power supply in their electronic designs. Its combination of low noise, low dropout, and low quiescent current makes it a versatile component for a wide range of applications.
