The LT1761ES5-SD#TRMPBF is a high-performance, low dropout linear regulator from Linear Technology, designed to deliver a continuous output current of up to 100mA with a low dropout voltage of just 300mV at full load. This regulator is well-suited for battery-powered applications due to its ultra-low quiescent current of only 20µA, which helps to extend battery life. Furthermore, in shutdown mode, the quiescent current reduces to less than 0.1µA, offering even greater power savings.

One of the standout features of the LT1761 series is its low output noise, which makes it ideal for sensitive RF supply applications and precision analog circuits. With an output noise level of only 20µV RMS over a 10Hz to 100kHz bandwidth when used with a 10nF bypass capacitor, the LT1761ES5-SD#TRMPBF ensures clean and stable power delivery.

This regulator is capable of operating over a wide input voltage range from 1.8V to 20V, providing the flexibility to be used in a variety of systems. It also offers excellent regulation characteristics, with a line regulation of 0.075% and load regulation of 0.1%, ensuring consistent output even with fluctuations in input voltage or variations in load.

The LT1761ES5-SD#TRMPBF comes in a compact SOT-23 package, making it an excellent choice for space-constrained applications. It also features overcurrent and overtemperature protection, enhancing the reliability and safety of the system it is used in. Additionally, the regulator provides a range of output voltages, from fixed outputs of 1.22V to 5V and adjustable outputs from 1.22V to 20V, offering versatility to designers.

With its combination of low noise performance, low quiescent current, and high output accuracy, the LT1761ES5-SD#TRMPBF is an excellent choice for portable electronics, wireless devices, and other applications where power efficiency and clean voltage supply are critical.
