LT1761ES5-2#TRM                                DESCRIPTION

The LT 1761 series are micropower low noiselow dropout regulators. With an external 0.01uFbypass capacitor output noise drops to 20uVs over a 10Hz to100kHz bandwidth. Designed for use in battery-powered systems,the low 20uA quiescent current makes them an ideal choice. In shutdown,quiescent current drops to less than 0.1uA.The devices are capable of operating over an input voltage from 1.8Vto20Vandcan supply 100mAof output current with a dropoutvoltageof300mVQuiescent current is well controlled.not rising in dropout as it does with many other regulators.
