LTC1844ES5-25 DESCRIPTION
The LTC1844 Series are low noise VLDO(very low dropout)linearregulators designedforlowpower/portable applications. These regulators can operate from input voltages as low as 1.6vTypical output noise isonly30uVms and typical dropout for theLTC1844-3.3 is just90mVatthe maximumloadcurrentof150mAreucingto30mVat 50mA.
