5V reference for industrial and instrumentation rails
The REF02CESA+T is a 5V fixed-output series voltage reference from the REF02 family, in an 8-SOIC package. It delivers 21 mA of output current with ±1% initial accuracy and a temperature coefficient of 65 ppm/°C over the -40°C to 85°C industrial range.
The 21 mA output current is the headline number for sourcing decisions. It can directly bias multiple op-amp rails or feed the reference input of a SAR ADC without a separate buffer — but if your load exceeds 21 mA total, you need an external buffer or a higher-current reference.
