The LT1761IS5-3#TRPBF is a micropower, low noise, low dropout linear voltage regulator manufactured by Analog Devices. It provides a fixed 3V output voltage and can supply up to 100mA of output current. Designed for battery-powered systems, it features a low quiescent current of 20µA and a very low shutdown current of less than 0.1µA.
Key electrical characteristics include a wide input voltage range from 1.8V to 20V and a low dropout voltage of 0.45V at 100mA. The regulator offers excellent noise performance, with output noise dropping to 20µVRMS over a 10Hz to 100kHz bandwidth when an external bypass capacitor is used. It also includes internal protection circuitry for overcurrent, overtemperature, and reverse polarity conditions.
The LT1761IS5-3#TRPBF is supplied in a small 5-lead TSOT-23 package, making it suitable for space-constrained applications. It is stable with output capacitors as low as 1µF, allowing for the use of small ceramic capacitors without the need for series resistance. This makes it an ideal choice for applications such as cellular phones, pagers, and wireless modems where low power consumption and low noise are critical.
This device is suitable for surface mount applications and operates within an ambient temperature range of -40°C to 125°C. Its fixed output voltage and robust protection features simplify circuit design and enhance reliability.
