ADR39x Products Part Number Nominal Output Voltage (V) ADR390 ADR391 ADR392 ADR395 2.048 2.500 4.096 5.000 GENERAL DESCRIPTION The ADR390, ADR391, ADR392, and ADR395 are precision 2.048 V, 2.5 V, 4.096 V, and 5 V band gap 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 battery-powered applications. The VOUT Sense Pin enables greater accuracy by supporting full Kelvin operation in PCBs employing thin or long traces. The ADR390, ADR391, ADR392, and ADR395 are micropower, low dropout voltage (LDV) devices that provide a stable output voltage from supplies as low as 300 mV above the output voltage. ADR390 and ADR391 are specified over the industrial range (–40∞C to +85∞C), while ADR392 and ADR395 are specified over the extended industrial range (–40∞C to +125∞C). 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 overcurrent protection.
