APL5309 - Voltage Regulator

Download the APL5309 datasheet PDF. This datasheet also covers the APL5308 variant, as both devices belong to the same voltage regulator family and are provided as variant models within a single manufacturer datasheet.

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.

Key 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 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-23-3, SOT-23-5, and SOT-8.
