General Description
The G994 is a high performance positive voltage regu-lator  designed  for  use  in  applications  requiring  very  low dropout voltage at up to 0.5 Amps. The G994 VO output  voltage  follows  the  4.0  times  of  VSET  voltage  until  it  reaches  VIN  voltage.  The  VSET  voltage  must  be larger than 1V to guarantee VO 4.0 times of VSET. An enable pin further reduces power dissipation while shut  down.  The  G994  provides  excellent  regulation  over variations in line, load and temperature.

The  G994  is  available  in  the  power  TO-252-5,  SOP-8  and SOP-8 with power pad package.
