Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the CCS8 grade meets the required 0.08% initial accuracy and 5 ppm/°C temperature coefficient specifications. Ensure the commercial temperature range of 0°C to 70°C aligns with the application environment requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this part for applications requiring a stable 3V reference with minimal quiescent current consumption. The low dropout characteristic ensures performance maintenance even with limited input voltage headroom. Consider the shutdown functionality if system power management is a priority. Verify that the 8-lead SO package fits the available board space constraints.
