LT1761ES5-1.8#TRMPBF, LDO Voltage Regulator, Fixed, 1.8 V to 20 V in, 0.3 V / 0.1 A out, TSOT-23-5

LT®1761 series is a micropower low noise/dropout regulator. With an external 0.01µF bypass capacitor, output noise drops to 20µVRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 20µA quiescent current makes them an ideal choice. In shutdown, quiescent current drops to less than 0.1µA. Quiescent current is well controlled, not rising in dropout as it does with many other regulators. Small ceramic capacitors can be used without the series resistance required by other regulators. Internal protection circuitry includes reverse battery protection, current limiting and thermal limiting. Typical applications are cellular phones, pagers, battery-powered systems, frequency synthesizers, wireless modems.
