300nA NanoPower Voltage References

ISL21080

The ISL21080 analog voltage references feature low supply

voltage operation at ultra-low 310nA typ, 1.5µA max operating

current. Additionally, the ISL21080 family features guaranteed

initial accuracy as low as ±0.2% and 50ppm/°C temperature

coefficient.

These references are ideal for general purpose portable

applications to extend battery life at lower cost. The ISL21080 is

provided in the industry standard 3 Ld SOT-23 pinout.

The ISL21080 output voltages can be used as precision voltage

sources for voltage monitors, control loops, standby voltages for

low power states for DSP, FPGA, Datapath Controllers,

microcontrollers and other core voltages: 0.9V, 1.024V, 1.25V,

1.5V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V and 5.0V.

Special Note: Post-assembly x-ray inspection may lead to permanent

changes in device output voltage and should be minimized or avoided.
