LT1761MPS5-3.3#TRMPBF - Low Noise, Low Dropout Voltage Regulator

The LT1761MPS5-3.3#TRMPBF is a high-performance, low dropout voltage regulator from Linear Technology, designed to deliver a fixed output of 3.3 volts with an output current up to 100mA. This device is part of the LT1761 series, known for its low noise and excellent power supply rejection ratio (PSRR), making it an ideal choice for noise-sensitive applications such as RF and precision analog circuits.

One of the standout features of this voltage regulator is its low quiescent current, which is typically only 20μA. This characteristic is particularly beneficial for battery-powered devices, as it helps to extend battery life by minimizing power consumption when the device is in standby mode. Additionally, the LT1761MPS5-3.3#TRMPBF boasts a low dropout voltage of merely 300mV at full load, ensuring efficient operation even when the input voltage is close to the output voltage.

The device comes in a compact SOT-23 package, which is suitable for space-constrained applications. It is also characterized by its fast transient response, which allows it to maintain stable output voltage even during rapid changes in load current. This makes it a reliable choice for applications that experience dynamic load conditions.

Moreover, the LT1761MPS5-3.3#TRMPBF incorporates several protective features to ensure long-term reliability and stability. These include overcurrent protection, which prevents the device from damage during overload conditions, and thermal shutdown, which protects the regulator from excessive temperature rises.

This voltage regulator is designed to work with a wide range of input voltages, from 1.8V to 20V, providing designers with flexibility in various power supply designs. The LT1761MPS5-3.3#TRMPBF is also fully specified over the temperature range of -40°C to 125°C, making it suitable for industrial and automotive applications where temperature extremes are common.

In summary, the LT1761MPS5-3.3#TRMPBF from Linear Technology is a robust, efficient, and versatile voltage regulator that offers low noise performance and excellent power supply rejection, ideal for high-precision electronic applications.
