G916 台湾致新代理商 GMT LDO系列 单电源LDO
300mA High PSRR, Low Noise, LDO Regulators

GeneralDescription
The  G916  series  is  a  low  supply  current,  high  PSRR,  low noise, and low dropout linear regulator that comes in    a    space    saving    TSOT-23-5,    SOT-23-5    &    SC-70-5(SOT-353)   package.   The   supply   current   at   no-load is 90μA. In the shutdown mode, the maximum supply  current  is  less  than  1μA.  Operating  voltage  range is from 2.5V to 6.0V. The over-current protection limit  is  set  at  550mA  typical.  An  over-  temperature  protection  circuit  is  built-in  in  the  Device  to  prevent  thermal  overload.  These  power  saving  features  make  the  G916  series  ideal  for  use  in  the  battery-powered  applications   such   as   notebook   computers,   cellular   phones, and PDA’s.

The  G916  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.  G916-XXX is with fixed-mode output. The output voltage range is from 1.2V to 5.0V.
