The LT1761ES5-3.3#TRMPBF is an ultra low-noise, micropower linear regulator in SOT-23 package manufactured by Analog Devices. This 3.3V LDO regulator is ideal for use in portable devices, as it is capable of providing up to 100mA of current while maintaining low noise output signal. This regulator boasts an excellent load regulation of 0.3mV/mA with an input-output variation of 1.2mV/mA. The package size is small enough to fit in the tightest of applications, at a rate of 1.3mm x 2.9mm. It also includes various protection features such as over voltage, over current and short circuit protection. This regulator is designed to meet the most stringent of requirements for noise, ripple rejection and quiescent current at high load currents. Further, it operates from input voltages ranging from 4.5V to 12V and is compliant with the RoHS directive.
