G9001 台湾致新代理商 GMT LDO系列 单电源LDO
500mA Low-Dropout Linear Regulators

General Description
The G9001 is a low supply current, low dropout linear regulator.  The  supply  current  at  no-load  is  100μA.  In  the  shutdown  mode,  the  maximum  supply  current  is  less than 1μA. Output current minimum limit is 500mA, and  over-current  protection  limit  is  set  at  860mA  typi-cal.  An  overtemperature  protection  circuit  is  built-in  in  the  G9001  to  prevent  thermal  overload.  These  power  saving  features  make  the  G9001  ideal  for  use  in  the  battery-powered  applications  such  as  notebook  com-puters, cellular phones, and PDA’

These  devices  feature  a  shutdown  function  and  are  offered  in  active  low  with  auto  discharge.  The  G9001  is  specifically  designed  to  employ  ceramic  output  ca-pacitors. The G9001 comes in a space saving SOT-89, SOT-23, SOT-23-5 and TSOT-23-5 package.
