Product Summary

The LT1761ES5-2.5 is a micropower, low noise, low dropout regulator. With an external 0.01mF bypass capacitor, output noise drops to 20mVRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 20mA quiescent current makes them an ideal choice. In shutdown, quiescent current drops to less than 0.1mA. The LT1761ES5-2.5 is capable of operating over an input voltage from 1.8V to 20V, and can supply 100mA of output current with a dropout voltage of 300mV. Quiescent current is well controlled, not rising in dropout as it does with many other regulators. The LT1761ES5-2.5 regulator is a stable with output capacitor as low as 1mF. Small ceramic capacitor can be used without the series resistance required by other regulators.
