LT1761 Series LDO Micropower FEATURES

LT1761 Series11761sff TYPICAL APPLICATION DESCRIPTION100mA, Low Noise,LDO MicropowerRegulators in TSOT-23 The LT 1761 Series are Micropower , low noise, low dropout regulators. With an external F bypass capacitor, output noise drops to 20 VRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 20 A quiescent current makes them an ideal choice. In shutdown, quiescent current drops to less than A. The devices are capable of operating over an input voltage from to 20V, and can supply 100mA of output current with a dropout voltage of 300mV. Quiescent current is well controlled, not rising in dropout as it does with many other LT1761 regulators are stable with output capacitors as low as 1 F. Small ceramic capacitors can be used without the Series resistance required by other protection circuitry includes reverse battery protection, current limiting, thermal limiting and reverse current protection.

The LT®1761 series are micropower, low noise, low dropout regulators. With an external 0.01μF bypass ... and as an adjustable device with a 1.22V reference voltage. The LT1761 regulators are available in the 5-lead TSOT-23 package. 5V Low Noise Regulator ... n No Protection Diodes Needed n Overcurrent and Overtemperature Protected
