Procurement Notes

Verify the specific ordering suffixes against official manufacturer documentation to confirm exact electrical characteristics, temperature ranges, and packaging options. Confirm RoHS compliance status and lead-free requirements prior to procurement. Ensure the selected variant matches the required initial accuracy and operating temperature specifications for the intended application environment.

Selection Notes

Select this component when a compact footprint is required alongside stable voltage referencing in power-constrained designs. The wide operating current range allows flexibility in source resistance calculations. Verify that the thermal dissipation limits are not exceeded at maximum ambient temperatures and load currents to maintain junction temperature within safe operating boundaries.

Part Context
