WL2801E28-5/TR

WL2801E WL2801E Low noise, High PSRR, High speed, CMOS LDO Http://www.willsemi.com Descriptions The WL2801E series is a high accuracy, low noise, high speed, low dropout CMOS Linear regulator with high ripple rejection. The devices offer a new level of cost effective performance in cellular phones, laptop and notebook computers, and other portable devices. The current limiter's fold-back circuit also operates SOT-23-5L as a short circuit protection and an output current limiter at the output pin. The WL2801E regulators are available in standard SOT-23-5L packages. Standard products are Pb-free and Halogen-free. Features  Input voltage : 2.7V~5.5V  Output range : 1.2V~3.3V  Output current : 200mA (@Vout2V)( Typ.)   PSRR : 75dB @ 217Hz  Dropout voltage : 170mV @ IOUT=200mA  Quiescent current : 70μA Typ.  Shut-down current : < 0.1μA  Recommend capacitor : 1uF **** **** Applications  MP3/MP4 Players  Cellphones, radiophone, digital cameras  Bluetooth, wireless handsets  Others portable electronics device For detail marking information, please see page 10.
