LT1460-10 Micropower Precision Series Reference

DESCRIPTION
The LT ®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 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 LT1460-10 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).

The q denotes specifications which apply over the specified temperature range. Note 1: If the part is stored outside of the specified temperature range, the output may shift due to hysteresis. Note 2: ESD (Electrostatic Discharge) sensitive device. Extensive use of ESD protection devices are used internal to the LT1460-10, however, high electrostatic discharge can damage or degrade the device. Use proper ESD handling precautions.
Note 3: Temperature coefficient is measured by dividing the change in output voltage by the specified temperature range. Incremental slope is also measured at 25°C. Note 4: Load regulation is measured on a pulse basis from no load to the specified load current. Output changes due to die temperature change must be taken into account separately. Note 5: Thermal regulation is caused by die temperature gradients created by load current or input voltage changes. This effect must be added to normal line or load regulation. This parameter is not 100% tested.
