ADR381ARTZ-R2

ADR381 is a precision 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 make this ideal for 3V to 5V battery-powered applications. This is micropower, low dropout voltage (LDV) device that provides a stable output voltage from supplies as low as 300mV above the output voltage. Typical applications are battery-powered instrumentation, portable medical instruments, data acquisition systems, industrial process control systems, hard disk drives, automotive.
