APL5301 datasheet



The APL5301, APL5302 series are micropower, low noise, low dropout linear regulators, which operate from 3V to 6V input voltage and deliver up to 300mA. Typical dropout voltage is only 260mV at 300mA loading. Designed for use in battery-powered system, the low 50uA
quiescent current makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the deivce maintain 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.


• Low Quiescent Current : 50uA (No load)

• Low Dropout Voltage : 400mV (VOUT(Nominal)=3.0V Version @300mA)

• Very low Shutdown Current : < 0.5uA

• Fixed Output Voltage : 1.3V ~ 5.0V by step 0.1V increment

• Stable with 1uF Output Capacitor

• Stable with Aluminum, Tantalum or Ceramic Capacitors

Applicatons :
• Notebook Computer
• PDA or Portable Equipments

• Noise-Sensitive Instrumentation Systems
