Product details

5 V reference with ±0.05% initial accuracy

Input headroom and load drive

The REF5050ID accepts an input voltage from 5.2 V to 18 V and can source up to 10 mA of output current. The 200 mV minimum dropout means a 5 V rail with ±5% tolerance still leaves enough headroom for regulation. Quiescent supply current is 1.2 mA typical, which matters for battery-powered or loop-powered designs where every milliamp counts.

Housed in an 8-pin SOIC package (0.154" width, 3.90 mm body), surface-mount assembly with standard reflow profiles.

Frequently asked questions

Is REF5050ID compatible with REF5045?

The REF5045 is the 4.5 V output variant in the same REF50xx family. Both share the same pinout and SOIC-8 footprint, so they are footprint-compatible but not function-compatible — the output voltage differs. If your design needs 5 V, the REF5050ID is the correct choice; the REF5045 cannot be substituted without changing the system reference voltage.
