The ADR390 and ADR391 are precision 2.048 V and 2.5 V bandgap voltage references featuring high accuracy and stability and low power consumption in a tiny footprint. Patented temperature drift curvature correction techniques minimize nonlinearity of the voltage change with temperature. The wide operating range and low power consumption with additional shutdown capability make them ideal for 3 V to 5 V battery-powered applications. The VOUT Sense Pin enables greater accuracy by supporting full Kelvin operation in systems using very fine or long circuit traces. The ADR390 and ADR391 are micropower, Low Dropout Voltage (LDV) devices that provide a stable output voltage from supplies as low as 300 mV above the output voltage. They are specified over the industrial (40C to +85C) temperature range. Each is available in the tiny 5-lead SOT-23 package. The combination of VOUT sense and shutdown functions also enables a number of unique applications combining precision reference/regulation with fault decision and over-current protection. Details are provided in the applications section.
