Figure 2. Supply Current (A) vs. Supply Voltage (V) GENERAL DESCRIPTION The AD1582/AD1583/AD1584/AD1585 series mode devices The AD1582/AD1583/AD1584/AD1585 are low cost, low power, source or sink up to 5 mA of load current and operate efficiently low dropout, precision band gap references. These designs are with only 200 mV of required headroom supply. These parts available as 3-terminal (series) devices and are packaged in the draw a maximum 70 A of quiescent current with only a compact SOT-23, 3-lead surface-mount package. The versatility 1.0 A/V variation with supply voltage. The advantage of of these references makes them ideal for use in battery-powered these designs over conventional shunt devices is extraordinary. 3 V or 5 V systems where there can be wide variations in supply Valuable supply current is no longer wasted through an input voltage and a need to minimize power dissipation. series resistor, and maximum power efficiency is achieved at The superior accuracy and temperature stability of the AD1582/ all input voltage levels. AD1583/AD1584/AD1585 result from the precise matching and The AD1582/AD1583/AD1584/AD1585 are available in two thermal tracking of on-chip components. Patented temperature grades, A and B, and are provided in a tiny footprint, the SOT- drift curvature correction design techniques minimize the 23. All grades are specified over the industrial temperature nonlinearities in the voltage output temperature characteristic. range of 40C to +125C. Table 1.
