EC8320 – 2A Low Dropout Regulator with Enable

General description

The EC8320  is a high performance positive  voltage regulator  designed  for use in applications  requiring very low Input voltage and very low dropout voltage at up to 2 amps. It operates with a VIN as low as 1.6V and VPP voltage 5V  with  output  voltage programmable as low as 0.8V.The EC8320 features ultra low dropout,ideal for applications where VOUT is very close to  VIN. Additionally,the EC8320 has an enable pin to further reduce power dissipation while shutdown.The EC8320 provides excellent regulation over variations in line,load and temperature.The EC8320 provides a power OK signal to indicate  if the voltage level of VO reaches 92% of its rating value. The EC8320 is available in the power SOP-8(Exposed PAD) package.  It is available with 1.2V, 1.5V,  1.8V  and 2.5V  internally  preset  outputs  that  are  also  adjustable using external resistors.
