Product Details

The SGM2019 series low-power, low-noise, low-dropout,CMOS  linear  voltage  regulators  operate  from  a  2.5V  to  5.5V  input  voltage.  They  are  the  perfect  choice  for  low  voltage,  low  power  applications.  A  low  ground  current  makes  this  part  attractive  for  battery  operated  power systems.   The   SGM2019   series   also   offer   ultra   low dropout   voltage   to   prolong   battery   life   in   portable electronics.  Systems  requiring  a  quiet  voltage  source, such  as  RF  applications,  will  benefit  from  the  SGM2019 series’ ultra low output noise (30μVRMS) and high PSRR. An  external  noise  bypass  capacitor  connected  to  the device’s BP pin can further reduce the noise level.

The output  voltage  is  preset  to  voltages  in  the  range  of 1.2V  to  5.0V.  Other  features  include  a  10nA  logic-controlled  shutdown  mode,  foldback  current  limit  and thermal shutdown protection.

The SGM2019 is available  in  GreenSOT-23-5  and SC70-5 packages. It  operates over an ambient  temperature range of -40°C to +85°C.
