LT1962EMS8#PBF

LT1962EMS8#PBF is a micropower, low noise, low dropout regulator. Designed for use in battery-powered systems, the low 30µA 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 LT1962 regulator 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. This 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. Applications include cellular phones, battery-powered systems, noise-sensitive instrumentation systems.
