DESCRIPTIO
The LT®1460-2.5 is a micropower bandgap reference that
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, 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-
2.5 does not require an output compensation capacitor, but
it is stable with capacitive loads. 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 and being damaged.
The LT1460-2.5 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 LT1460S3-2.5).
