GENERAL DESCRIPTION
The AD1582, AD1583, AD1584 and AD1585 are a family of
low cost, low power, low dropout, precision bandgap references.
These designs are available as three-terminal (series) devices and
are packaged in the compact SOT-23, 3-pin, 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 have
been used to minimize the nonlinearities in the voltage output
temperature characteristic.
These series mode devices (AD1582/AD1583/AD1584/AD1585)
will source or sink up to 5 mA of load current and operate
efficiently with only 200 mV of required headroom. This family
will draw a maximum 65
μ
A of quiescent current with only a
1.0
μ
A/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
two grades, A and B, both of which are provided in the smallest
available package on the market, the SOT-23. Both grades are
specified over the industrial temperature range of –40
°
C to
+85
°
C.
