The LT

combines very high accuracy and low drift with low power

dissipation and small package size. This series reference

uses curvature compensation to obtain a low temperature

coefficient and trimmed precision thin-film resistors to

achieve high output accuracy. 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 LT1460-10

does not require an output capacitor, but it is stable with

capacitive loads. This feature is important in critical applica-

tions where PC board space is a premium or fast settling is

demanded. Reverse battery protection keeps the reference

from conducting current and being damaged.

The LT1460-10 is available in the 8-lead MSOP, SO, PDIP

and the 3-lead TO-92 packages. It is also available in the

SOT-23 package; see separate data sheet LT1460S3-10

(SOT-23).
