It delivers a regulated 5V output from an input range of 8V to 30V, with a typical output current of 21 mA and a temperature coefficient of 250 ppm/°C over the 0°C to 70°C commercial range. This part is commonly used to bias the reference input of an ADC, set the regulation point of a downstream linear regulator, or provide a stable 5V rail for analog signal chains in bench instruments, office equipment, and indoor control boards. ## 21 mA output — how many loads it can drive The 21 mA output current rating tells you how much total current the reference can supply to all loads on its output pin. ## 250 ppm/°C drift — what it means for accuracy The 250 ppm/°C temperature coefficient means the output voltage can shift by up to 250 parts per million for every degree Celsius change in junction temperature. ## Lifecycle and sourcing The REF02DSA is listed as Active in production, so there is no last-time-buy or obsolescence risk for new designs. Note that the part is RoHS non-compliant — it uses lead-bearing solder terminations — which may restrict its use in RoHS-mandated jurisdictions unless an exemption applies.","metaTitle":"REF02DSA 5V Voltage Reference, ±2% Tolerance, 8-SOIC","metaDescription":"REF02DSA 5V fixed series voltage reference from the REF02 family. ±2% tolerance, 21 mA output, 250 ppm/°C tempco, 0°C to 70°C.
