Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRMPBF corresponds to the Tape and Reel (Mini) packaging configuration containing 500 pieces as defined in the official order information tables. Confirm that the H grade designation aligns with the required 0.2% accuracy and 20ppm/°C temperature coefficient specifications for the target application environment.

Voltage Reference Selection Notes

Select this component when a compact SOT-23 package is required alongside micropower consumption levels suitable for battery-operated systems. The 5V output option is appropriate for interfacing with standard logic families or ADCs requiring a stable positive reference. Ensure the minimum input-to-output differential of 0.9V is maintained across all expected operating conditions.

Voltage Reference Part Context

This part belongs to the LT1460 family of micropower series references available in multiple packages including SOT-23, TO-92, SO-8, MSOP-8, and PDIP-8. The HCS3 variant specifically denotes the commercial temperature grade housed in the 3-lead plastic SOT-23 package.
