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
drive makes them suitable for higher power requirements,
such as precision regulators.
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.
