APL5901

APL5901/2 Low IQ, Low Dropout 900mA Fixed Voltage Regulator Features Low Noise : 50µVRMS (100Hz to 100kHz) Low Quiescent Current : 50µA (No load) Low Dropout Voltage : 210mV (@900mA) Very low Shutdown Current : < 1µA Fixed Output Voltage : 1.3V ~ 3.4V www.DataSheet4U.com Stable with 4.7µF Output Capacitor Stable with Aluminum , Tantalum or Ceramic Capacitors . Reverse Current Protection No Protection Diodes Needed Built in Thermal Protection Built in Current Limit Protection Controlled Short Circuit Current : 200mA Fast Transient Response Short Setting Time SOT-89, SOT-89-5, SOT-223, SO-8 ,TO-252 and TO-252-5 Packages Lead Free Available (RoHS Compliant) Design with an internal P-channel MOSFET pass transistor, the APL5901/2 maintains a low supply current, independent of the load current and dropout voltage. Other features include reverse current protection, thermal-shutdown protection, current limit protection to ensure specified output current and controlled short-circuit current. The APL5901/2 regulator come in a miniature SOT-89, SOT-89-5, SOT-223, SO8, TO-252 and TO-252-5 packages.
