LT1763CS8-2.5#TRPBF

LT1763CS8-2.5#TRPBF is a micropower, low noise, low dropout regulator. The devices are capable of supplying 500mA of output current with a dropout voltage of 300mV. 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 LT1763 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. The LT1763 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. Typical applications include cellular phones, battery-powered systems, noise-sensitive instrumentation systems.
