Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates mini tape and reel packaging containing 500 pieces. Confirm the 'C' grade designation aligns with commercial temperature specifications (0°C to 70°C) rather than industrial grades. Ensure the component matches the required lead-free finish and RoHS compliance standards before finalizing procurement orders.

Voltage Reference Selection Notes

Select this part when a fixed 3V reference is required with high precision and minimal power consumption. The TSOT-23 package suits space-constrained designs. Verify that the input voltage remains above the minimum dropout threshold under all load conditions. Consider the 5mA sourcing capability for direct ADC driving applications without additional buffering.

Voltage Reference Part Context

This component belongs to the LT6656 family of 1µA precision series voltage references. The family offers various output voltages including 1.25V, 2.5V, and 5V options across different packages like DFN and LS8. The ACS6 variant specifically denotes the commercial temperature grade housed in the compact 6-lead plastic TSOT-23 surface-mount package.
