The AD1582, AD1583, AD1584, and AD1585 are a family of low cost, low power, low dropout, precision band gap references. These designs are available as three-terminal (series) devices and are packaged in the compact SOT-23, 3-lead surface-mount package. The versatility of these references makes them ideal for use in battery-powered 3 V or 5 V systems where there may be wide variations in supply voltage and a need to minimize power dissipation.
