ISL21080

300nA NanoPower Voltage References

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: 1.25V,

1.5V, 2.5V, and 3.3V.
