ISL21080

300nA NanoPower Voltage References

DATASHEET

The ISL21080 analog voltage references feature low supply

voltage operation at ultra-low 310nA typical, 1.5µA maximum

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. For further information, please see “Applications

Information” on page 15 and AN1533, “X-Ray Effects on Intersil FGA

References”.
