APL5551

APL5551 Dual Channel 500mA/500mA Regulator + Reset IC Features • • Low Quiescent Current : 110µA (No load) Low Dropout Voltage : VDROP1 = 450mV @ 500mA VDROP2 = 500mV @ 500mA • Fixed Output Voltage : VOUT1 = 3.3V/500mA VOUT2 = 2.8V/500mA • • • • • • • • • Stable with 4.7µF Output Capacitor Stable with Aluminum, Tantalum or Ceramic Capacitors Built in Thermal Protection Fast Transient Response Short Setting Time SOP-8, SOP-8-P with Thermal Pad Packages Adjustment-free Reset Detection Voltage : 3.9V typ Easy to Set Delay Time from Voltage Detection to Reset Release Lead Free Available (RoHS Compliant) General Description The APL5551 is a dual-channel regulator with reset function (specific voltage monitoring), and internal delay circuit, set to detect 3.9V. Maximum input voltage is 6V, and both output1 and output2 can deliver up to 450mA. The typical dropout voltage of both channel is 500mV at 500mA loading. Design with an internal P-channel MOSFET pass transistor, the APL5551 maintains a low supply current. Other features include, thermal-shutdown protection, current limit protection to ensure specified output current. The APL5551 comes in miniature SOP-8 and SOP-8-P packages.
