LT1962EMS8-3.3#PBF Datasheet PDF - Linear Technology

●The LT1962EMS8-3.3#PBF is a 3.3V 300mA low noise micropower Low Dropout Regulator capable of supplying 300mA of output current with a dropout voltage of 270mV. Designed for use in battery-powered systems, the low 30µA 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. A key feature of the LT1962 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 LT1962 regulator is stable with output capacitors as low as 3.3µF. 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 1.5, 1.8, 2.5V, 3, 3.3 and 5V and as an adjustable device with a 1.22V reference voltage.
