G964 台湾致新代理商 GMT LDO系列 双电源LDO
1A Low Dropout Regulator with Enable

General Description
The  G964  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 1 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  G964  features  ultra  low  dropout,  ideal  for  applications  where  VOUT  is  very  close  to  VIN. Additionally,  the  G964  has  an  enable  pin  to  further  reduce  power  dissipation  while  shutdown.  The  G964  provides  excellent  regulation  over  variations  in  line,  load and temperature. The G964 provides a power OK signal  to  indicate  if  the  voltage  level  of  VO  reaches  92% of its rating value.

The G964 is available in the power SOP-8 package. It is  available  with  1.2V,  1.5V,  1.8V  and  2.5V  internally  preset  outputs  that  are  also  adjustable  using  external  resistors.
