Description

The LT^®1460S3-5 is a SOT-23 micropower series reference that combines high accuracy and low drift with low power dissipation and small package size. This series reference uses curvature compensation to obtain low temperature 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. The reference will supply up to 20mA, making it ideal for precision regulator applications, yet it is almost totally immune to input voltage variations.

This series reference provides supply current and power dissipation advantages over shunt references that must idle the entire load current to operate. Additionally, the LT1460S3-5 does not require an output compensation capacitor, but is stable with any capacitive load. This feature is important in critical applications where PC board space is a premium or fast settling is demanded. Reverse-battery protection keeps the reference from conducting current.

For even tighter tolerance and lower temperature coefficient, the LT1460 is also available in the 8-lead MSOP, SO, PDIP and the 3-lead TO-92 packages. A 2.5V version is also available.
