Low 25uVrms Noise Linear Regulator Paralleled For Higher Output Current

Low 25uVrms Noise Linear Regulator Paralleled For Higher Output Current

The LT1762 series are micropower, low noise, low dropout regulators. The devices are capable of supplying 150mA of output current with a dropout voltage of 270mV. Designed for use in battery-powered systems, the low 25μA quiescent current makes them an ideal choice. Quiescent current is well controlled; it does not rise in dropout as it does with many other regulators. A key feature of the LT1762 regulators is low output noise. With the addition of an external 0.01μF bypass capacitor, output noise drops to 20μVRMS over a 10Hz to 100kHz bandwidth. The LT1762 regulators are stable with output capacitors as low as 2.2μF. Small ceramic capacitors can be used without the series resistance required by other regulators.
