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.
