Micropower Precision

Series Reference Family

combines very 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 trimmed precision thin-film resistors to

achieve high output accuracy. The reference will supply

up to 20mA with excellent line regulation characteristics,

making it ideal for precision regulator applications.

This series reference provides supply current and power

dissipationadvantagesovershuntreferencesthatmustidle

the entire load current to operate. Additionally, the LT1460

does not require an output compensation capacitor, yet

is stable with capacitive loads. This feature is important

where PC board space is a premium or fast settling is

demanded. In the event of a reverse battery connection,

thesereferenceswillnotconductcurrent,andaretherefore

protected from damage.

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

the 3-lead TO-92 and SOT23 packages.
