25µA Micropower Voltage References
ISL21070
The ISL21070 voltage references are analog voltage
references featuring low supply voltage operation at
ultra-low 25µA max operating current.
Additionally, the ISL21070 family features guaranteed
initial accuracy as low as ±0.2% and 30ppm/°C
temperature coefficient.
These references are ideal for general purpose
applications for performance at lower cost. The ISL21070
is provided in an industry standard 3 Ld SOT-23 pinout.
The ISL21070 offers output voltages that can be used as
precision voltage sources for control loops, standby
voltages for low power states for DSP, FPGA, Datapath
Controllers, Microcontrollers and other core voltages:
1.024V, 2.048V, 2.5V, and 3.3V.
