Featuring +125°C, the ADR130 is housed in a tiny TSOT package. 0.35% initial accuracy and 25 ppm/°C of temperature drift in For 0.5 V output, tie SET (Pin 5) to V (Pin 4). For 1.0 V OUT the tiny TSOT-23 package, the ADR130 voltage reference only output, tie SET (Pin 5) to GND (Pin 2). requires 80 μA for typical operation. The ADR130 design includes a proprietary temperature drift curvature correction technique that minimizes the nonlinearities in the output voltage vs. temperature characteristics. Rev.
