APL5308数据手册Anpec中文资料规格书

描述 Description

The APL5308/9 series are micropower, low dropout lin ear regulators, which operate from 2.7V to 6V input voltage and  del i ver up to  300mA. Typical  dropout  voltage is  only  400mV  at  300mA  l oadi ng. Desi gned  for   use  in battery-powered  system,  the low  60mA  qui escent 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   p rotection  current   limit   protection to   ensure specified  output current and controlled  short-circuit current . The APL5308/ 9  regulators  come  in  a  miniature SOT-23-3, SOT-23-5, and SOT-89 packages.
