GENERAL DESCRIPTION

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.

The superior accuracy and temperature stability of the AD1582/
AD1583/AD1584/AD1585 is made possible by the precise
matching and thermal tracking of on-chip components. Patented
temperature drift curvature correction design techniques minimize
the nonlinearities in the voltage output temperature characteristic.

These series mode devices (AD1582/AD1583/AD1584/AD1585)
source or sink up to 5 mA of load current and operate efficiently
with only 200 mV of required headroom supply. This family
draws 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, and AD1585 are available in
three grades, A, B, and C, 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.
