APL5508

APL5508/5508R/5509/5509R Low IQ, Low Dropout 560mA Fixed Voltage Regulator Features Low Quiescent Current : 60µA (No load) Low Dropout Voltage : 600mV (@560mA) Very Low Shutdown Current : < 0.5µA Fixed Output Voltage : 1.5V ~ 4.5V by Step 0.1V Increment Stable with Aluminum, Tantalum, or Ceramic Capacitors No Protection Diodes Needed Built-In Thermal Protection Built-In Current-Limit Protection Controlled Short Circuit Current : 50mA Fast Transient Response SOT-23-3, SOT-89, and SOT-223 Packages Lead Free and Green Devices Available (RoHS Compliant) Pin Configuration General Description The APL5508/5508R/5509/5509R is low-power and low dropout linear regulator, which operates in the rage of 2.7V to 6V input voltage and delivers up to 560mA output current. Typical dropout voltage is only 600mV (typical) at 560mA output current. The APL5508/5508R/5509/5509R regulator with low 60µA quiescent current is ideal for battery powered system appliances. The APL5508/5508R/ 5509/5509R regulator is stable with a 4.7µF ceramic capacitor. The features of current-limit, short circuit current limit, and over-temperature protection protect the device against current over loads and over temperature. The APL5508/5508R/5509/5509R regulator is available in SOT-23-3, SOT-89, or SOT-223 packages.
