GENERAL DESCRIPTION

The ADR318 is a precision 1.8 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 a

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.

See the Applications section for details.
