The LT®1761 series are micropower, low noise, low dropout regulators that provide 100mA of output current in SOT-23 packages. The series features 20µVRMS of low noise, 20µA of low quiescent current, a wide input voltage range of 1.8V to 20V, 300mV of low dropout, and <0.1µA of extremely low shutdown current. Fixed output voltages are available at 1.2V, 1.5V, 1.8V, 2V, 2.5V, 2.8V, 3V, 3.3V, and 5V. Adjustable output voltage ranges from 1.22V to 20V. The series is stable with 1µF of output capacitance and operates with aluminum, tantalum, or ceramic capacitors. The series provides reverse battery protection, no reverse current, no need for protection diodes, and overcurrent and overtemperature protection. The series is available in a tiny 5-lead SOT-23 package.
The LT1761 regulators are micropower, low‑noise, low‑dropout devices designed for battery‑powered systems. They operate from 1.8 V to 20 V input and can deliver up to 100 mA output while maintaining a low quiescent current and very low shutdown current.
Key features include reverse‑battery protection, over‑current and over‑temperature protection, and stability with 1 µF output capacitors of various types. Fixed output versions are available from 1.2 V to 5 V, and an adjustable version provides output from 1.22 V to 20 V.
