APL5501 datasheet



The APL5501, APL5502, APL5503 are micropower, low noise, low drop out linear regulators. Operate from 2.7V to 6V input voltage and deliver up to 500mA. Typical output noise is just 50mV RMS with the addition of an external 0.1mF bypass capacitor in BP pin and  typical dropout  voltage  is  only  170mV at  500mA loading. Designed for use in battery-powered system, the low 50mA quiescent current makes it an ideal choice.


1. Low Noise : 50mVRMS (100Hz to 100kHz)

2. Low Quiescent Current : 50mA (No load)

3. Low Dropout Voltage : 170mV (@500mA)

4. Very Low Shutdown Current : < 0.5mA

5. Fixed Output Voltage : 1.3V ~ 3.4V

6. Stable with 4.7mF Output Capacitor



1. Notebook Computer

2. PDA or Portable Equipments

3. Noise-Sensitive Instrumentation Systems
