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, Data path Controllers,
Microcontrollers and other core voltages: 0.600V, 2.048V, and
2.5V.
Applications
• Battery management/monitoring
• Low power standby voltages
• Portable instrumentation
• Consumer/medical electronics
• Wearable Electronics
• Lower Cost industrial and instrumentation
• Power regulation circuits
• Control loops and compensation networks
• LED/diode supply
