8 V band gap voltage reference featuring high accuracy, high 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 the part 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 ADR318 is a low dropout voltage (LDV) device that provides a stable output voltage from supplies as low as 600 mV above the output voltage.
This device is specified over the industrial operating range of 0°C to 70°C, and 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.
