DESCRIPTIO
The LT^®1460S3 is a family of SOT-23 micropower series
references that combine high accuracy and low drift with low
power dissipation and small package size. These series
references use curvature compensation to obtain low tem-
perature coefficient, and laser trimmed precision thin-film
resistors to achieve high output accuracy. Furthermore,
output shift due to PC board soldering stress has been
dramatically reduced. These references will supply up to
20mA, making them ideal for precision regulator applica-
tions, yet they are almost totally immune to input voltage
variations.
These series references provide supply current and power
dissipation advantages over shunt references that must idle
the entire load current to operate. Additionally, the
LT1460S3 does not require an output compensation capaci-
tor. This feature is important in applications where PC board
space is a premium or fast settling is demanded. Reverse-
battery protection keeps these references from conducting
reverse current.
