300nA Nano Power Voltage Reference, Fixed, 1.5V, SOT-23-3 - 

The ISL21080CIH315Z-TK is an Analogue Voltage Reference features 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. This reference is an ideal for general purpose portable applications to extend battery life at lower cost. The ISL21080 is provided in the industry standard 3 lead 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 voltage such as 0.9, 1.024, 1.25, 1.5, 2.048, 2.5, 3.0, 3.3, 4.096 and 5.0V.
