G9091 台湾致新代理商 GMT LDO系列 单电源LDO
300mA Low-Dropout Linear Regulators

General Description
The G9091 is a low supply current, low dropout linear regulator  that  comes  in  a  space  saving  SOT-23-5,  TSOT-23-5,   SC-70-4   (SC-82   /   SOT-343),   SC-70-5   (SOT-353), TDFN1.6X1.6-6, TDFN2X2-6 and TDFN2X2-8 package.  The  supply  current  at  no-load  is  100μA.  In  the  shutdown  mode,  the  maximum  supply  current  is  less  than  1μA.  The  over-current  protection  limit  is  set  at  430mA  typical.  An  overtemperature  protection  cir-cuit is built-in in the G9091 to prevent thermal overload. These  power  saving  features  make  the  G9091  ideal  for  use  in  the  battery-powered  applications  such  as  notebook computers, cellular phones, and PDA’s.

These  devices  feature  a  shutdown  function  and  are  offered  in  active  low  with  auto  discharge.  The  G9091  is  specifically  designed  to  employ  ceramic  output  ca-pacitors.   The   G9091   comes   in   a   space   saving   SOT-23-5,    TSOT-23-5,    SC-70-4(SC-82/SOT-343),    SC-70-5  (SOT-353),  TDFN1.6X1.6-6,  TDFN2X2-6  and TDFN2X2-8 package.
