GENERAL DESCRIPTION  
The AD1582/AD1583/AD1584/AD1585 series mode devices  
source or sink up to 5 mA of load current and operate efficiently  
with only 200 mV of required headroom supply. These parts  
draw a maximum 70 μA of quiescent current with only a  
1.0 μA/V variation with supply voltage. The advantage of  
these designs over conventional shunt devices is extraordinary.  
Valuable supply current is no longer wasted through an input  
series resistor, and maximum power efficiency is achieved at  
all input voltage levels.  
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.  
The superior accuracy and temperature stability of the AD1582/  
AD1583/AD1584/AD1585 result from the precise matching and  
thermal tracking of on-chip components. Patented temperature  
drift curvature correction design techniques minimize the  
The AD1582/AD1583/AD1584/AD1585 are available in two  
grades, A and B, and are provided in a tiny footprint, the SOT-  
23. All grades are specified over the industrial temperature  
range of −40°C to +125°C.
