GENERAL DESCRIPTION

The AD1582/AD1583/AD1584/AD1585 are low cost, low power, low dropout, precision band gap references. These designs are available as 3-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 can be wide variations in supply voltage and a need to minimize power dissipation.

FEATURES

Series reference (2.5 V, 3 V, 4.096 V, 5 V)

Low quiescent current: 70 μA maximum

Current output capability: ±5 mA

Wide supply range: VIN = VOUT + 200 mV to 12 V
