General Description
The  G9661  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 1.4V and VPP  voltage  5V  with  output  voltage  programmable  as  low  as  0.8V.  The  G9661  features  ultra  low  dropout,  ideal  for  applications  where  VOUT  is  very  close  to  VIN. Additionally,  the  G9661  has  an  enable  pin  to  further  reduce  power  dissipation  while  shutdown.  The  G9661  provides  excellent  regulation  over  variations  in  line,  load  and  temperature.  The  G9661  provides  a  power  OK signal to indicate if the voltage level of VO reaches 92% of its rating value.

The  G9661  is  available  in  the  power  TSOT-23-6,  SOP-8(FD), MSOP-10(FD) and TDFN3X3-10 package. It  is  available  with  2.5V  internally  preset  outputs  that  are also adjustable using external resistors.
