The LT1762EMS8-5#PBF is a 5V 150mA low dropout Micropower Regulator featuring low output noise. The device is capable of supplying 150mA of output current with a dropout voltage of 300mV. Designed for use in battery-powered systems, the low 25μA quiescent current makes it an ideal choice. Quiescent current is well controlled, it does not rise in dropout as it does with many other regulators. With the addition of an external 0.01μF bypass capacitor, output noise drops to 20μVRMS over a 10Hz to 100kHz bandwidth. The LT1762 regulator is stable with output capacitors as low as 2.2μF. Small ceramic capacitors can be used without the series resistance required by other regulators. Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting and reverse current protection. The parts come in fixed output voltages of 2.5, 3, 3.3 and 5V and as an adjustable device with a 1.22V reference voltage.
