DESCRIPTION:

The LM37100/1/2is1A low-dropout linear voltage regulators that provide low-voltage,high-current output. The LM37100/1/2  offers  extremely  low  dropout  (typically470mVat  1A)  and  lowground  current  (typically  12mAat 1A).The  LM37100/1  and  LM37102  arefixedand  adjustable  regulators,  respectively,  in SOT-223, SOP-8and TO-252Package. The LM37100/1/2 is ideal for  PC add-in cards that need toconvert  from standard 5V to 3.3V, 3.3V to 2.5Vor 2.5V  to1.8V.  A  guaranteed  maximum dropout  voltage  of  630mV  overall  operating  conditions  allows  theLM37100/1/2  to  provide2.5V  from  a  supply  as  low  as  3.13V  and  1.8V  from  a  supply  as  low  as  2.43V.The LM37100/1/2  is  fully  protected  with  over  current  limiting,thermal  shutdown,  and  reversed-batteryprotection. Fixed voltages of 5.0V, 3.3V, 2.5V,1.8V and 1.5V are available on LM37100/1 with adjustableoutput voltages to 1.24V on LM37102.
