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
V OUT (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
Rev. A

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 V OUT (SENSE) and shutdown functions also
enables a number of unique applications, combining precision
reference/regulation with fault decision and overcurrent
protection.
