The LT
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 35 A 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 immeasur-
able, while the exceedingly good load and thermal 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 conditions. The LT1461 is
available in 2.5V, 3V, 3.3V 4.096V and 5V options.
