GeneralDescription
The  G917  series  is  a  low  supply  current,  high  PSRR,  low noise, and low dropout linear regulator that comes in  a  space  saving  SOT-23-5  package.  The  supply  current  at  no-load  is  100μA.  In  the  shutdown  mode,  the maximum supply current is less than 1μA. Operat-ing   voltage   range   is   from   2.5V   to   6.0V.   The   over-current protection limit is set at 750mA typical. An over-  temperature  protection  circuit  is  built-in  in  the  Device  to  prevent  thermal  overload.  These  power  saving features make the G917 series ideal for use in the  battery-powered  applications  such  as  notebook  computers, cellular phones, and PDA’s.

The  G917  has  two  modes  of  operation.  When  the  SET  pin is connected to ground, its output is a pre-set value: 3.3V. There is no external component needed. When an output  other  than  the  preset  value  is  needed,  two  ex-ternal resistors should be used as a voltage divider. The output voltage is then adjusted by the resistor ratio.
