Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. or Maxim Integrated. Check RoHS compliance status as indicated in official documentation. Ensure the UCSP-5 package matches your PCB footprint requirements. Validate the 4.5 V output specification against your circuit design needs before procurement.

Selection Notes

Select this component when a fixed 4.5 V reference is required with high initial accuracy and low power consumption. The UCSP-5 package is ideal for dense PCB layouts. Consider the 30 ppm/°C temperature coefficient for applications operating between -40°C and +85°C. Ensure the load current does not exceed 500 µA. Verify input voltage compatibility within the 12.6 V maximum limit.

Part Context
