FeaTures  
DescripTion  
The LT®1461 is a family of low dropout micropower band-  
gap references that combine very high accuracy and low  
drift with low supply current and high output drive. These  
series references use advanced curvature compensation  
techniques to obtain low temperature coefficient and  
trimmed precision thin-film resistors to achieve high  
output accuracy. The LT1461 family draws only 35µA  
of supply current, making them ideal for low power and  
portable applications, however their high 50mA output  
drivemakesthemsuitableforhigherpowerrequirements,  
such as precision regulators.

applicaTions  
In low power applications, a dropout voltage of less than  
300mV ensures maximum battery life while maintaining  
full reference performance. Line regulation is nearly im-  
measurable, while the exceedingly good load and ther-  
mal regulation will not add significantly to system error  
budgets. The shutdown feature can be used to switch full  
load currents and can be used for system power down.  
Thermal shutdown protects the part from overload condi-  
tions. The LT1461 is available in 2.5V, 3V, 3.3V 4.096V  
and 5V options.
