G913C 台湾致新代理商 GMT LDO系列 单电源LDO
300mA Low-Dropout Linear Regulators

GeneralDescription
The  G913  is  a  low  supply  current,  low  dropout  linear  regulator  that  comes  in  a  space  saving  SOT-23-5  package. The supply current at no-load is 90μA. In the shutdown  mode,  the  maximum  supply  current  is  less  than 1μA. Operating voltage range of the G913 is from 2.5V to 5.5V. The over-current protection limit is set at 550mA  typical.  An  over-temperature  protection  circuit  is  built-in  in  the  G913  to  prevent  thermal  overload.  These power saving features make the G913 ideal for use in the battery-powered applications such as note-book computers, cellular phones, and PDA’s.

The G913 has two modes of operation. When the SET pin is connected to ground, its output is a pre-set value: 1.5V~4.7V   (interval   =100mV),   2.84V,   3.15V,   and   4.75V. There is no external component needed to de-cide the output voltage. When an output other than the preset  value  is  needed,  two  external  resistors  should  be  used  as  a  voltage  divider.  The  output  voltage  is  then decided by the resistor ratio. The G913 comes in a space saving SOT-23-5 package.
