PRODUCT DESCRIPTION
The  LP2950  and  LP2951  are  low  power  voltage  regulators.  These  devices  are  an  excellent  choice  for  use  in  battery-powered
applications  such  as  cordless  telephones,  radio  control  systems,  and  portable  computers.  The  LP2950  and  LP2951  feature  low
quiescent current and  low dropout voltage  (typ. 50mV at  light  load and 380 mV at 100mA). This  includes a  tight  initial  tolerance
(0.5%  typ.),  extremely good  load  and  line  regulation  (0.05%  typ.),  and very  low output  temperature  coefficient  (20 ppm/°C  typ.),
making the LP2950/LP2951 useful as a low-power voltage reference.
The error flag output feature is used as a power-on reset for warning of a low output voltage, due to a falling input voltage. The logic-
compatible  shutdown  feature enables  the  regulator  to be  switched ON and OFF. The LP2950  is offered  in a 3-pin TO-92 package
compatible with other 5V, 3.3V regulators. The LP2951 is available in an 8-lead SOIC package.
