Housed in an 8-SOIC package (0.154" body width, 3.90 mm), surface-mount solders directly to a standard SOIC-8 footprint. No heatsink is needed at the 1.6 mA quiescent draw, but derate output current if ambient approaches 85°C and the part is driving a heavy load.
The REF02 series has been a staple for decades; Maxim (now part of Analog Devices) continues to manufacture it, and the die is mature and stable.
The initial output voltage tolerance is ±1% at 25°C. Combined with the 65 ppm/°C temperature coefficient, the total error over the -40°C to 85°C range stays within roughly ±1.6% worst-case, assuming no load-regulation effects.
Yes, it is ROHS3 compliant, meaning it meets the latest EU RoHS directive with no exempted substances.
Within the same REF02 series, the REF02CS+ is a direct functional equivalent in the same 8-SOIC footprint with identical 5 V output and ±1% tolerance. The primary difference is the temperature range: REF02CS+ is rated 0°C to 70°C (commercial), while REF02CESA+ covers -40°C to 85°C (industrial). For a drop-in replacement with wider temperature range, the REF02CESA+ is the correct choice.
