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. For further information, please see

“Applications Information” on page 14 and AN1533 , “X-Ray

Effects on Intersil FGA References”.
