GENERAL DESCRIPTION
The ADR318
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
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
