The LT ®1460S3 is a family of SOT-23 micropower series references that combine high accuracy and low drift with low power dissipation and small package size. These series references use curvature compensation to obtain low temperature coefficient, and laser trimmed precision thin-film resistors to achieve high output accuracy. Furthermore, output shift due to PC board soldering stress has been dramatically reduced. These references will supply up to 20mA, making them ideal for precision regulator applications, yet they are almost totally immune to input voltage variations. These series references provide supply current and power dissipation advantages over shunt references that must idle t h e entire load current to operate. Additionally, the LT1460S3 does not require an output compensation capacitor. This feature is important in applications where PC board space is a premium or fast settling is demanded. Reversebattery protection keeps these references from conducting reverse current.

Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: The LT1460S3 is guaranteed functional over the operating temperature range of 40°C to 85°C. Note 3: If the parts are stored outside of the specified temperature range, the output may shift due to hysteresis.
Note 4: ESD (Electrostatic Discharge) sensitive devices. Extensive use of ESD protection devices are used internal to the LT1460S3, however, high electrostatic discharge can damage or degrade the device. Use proper ESD handling precautions. Note 5: Temperature coefficient is measured by dividing the change in output voltage by the specified temperature range. Incremental slope is also measured at 25°C.
