Description

The LT^(R) 1460-10 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 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).
