DATASHEET
ISL21080
300nA NanoPower Voltage References
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”.
