APL5309-45AC

APL5308/9 Low IQ, Low Dropout 300mA Fixed Voltage Regulator Features • • • • • • • • • • • • Low Quiescent Current : 60µA (No load) Low Dropout Voltage : 400mV (@300mA) Fixed Output Voltage : 1.5V ~ 4.5V by step 0.1V increment Stable with 1uF Output Capacitor 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 Short Setting Time SOT-23 ,SOT-23-5 and SOT-89 Packages General Description The APL5308/9 series are micropower, low dropout linear regulators, which operate from 2.7V to 6V input voltage and deliver up to 300mA. Typical dropout voltage is only 400mV at 300mA loading. Designed for use in battery-powered system, the low 60µA quiescent current makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the APL5308/9 maintain a low supply current, independent of the load current and dropout voltage. Other features include thermal-shutdown protection current limit protection to ensure specified output current and controlled short-circuit current. The APL5308/9 regulators come in a miniature SOT-23, SOT-23-5 and SOT-89 packages.
