General Description
The APL5508/9/R series are micropower, low dropout linear regulators, which operate from 2.7V to 6V input voltage and deliver up to 560mA. Typical dropout voltage is only 600mV at 560mA loading. Designed for use in battery-powered system, the low 60 A quiescent current makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the APL5508/9/R 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 APL5508/9/R regulators come in a miniature SOT23, SOT-89 and SOT-223 packages.
Applications
•5V to 3.3~4.3V Linear Regulators
•3.3V to 1.5~2.5V Linear Regulators
•CD-R/W, DVD Player
•LAN Card, ADSL/Cable Modem
•Computers
