微功耗电压基准 MICROPOWER VOLTAGE REFERENCES
description/ordering information
These micropower, two-terminal, band-gap voltage references operate over a 10-µA to 20-mA current range and feature exceptionally low dynamic impedance and good temperature stability. On-chip trimming provides tight voltage tolerance. The band-gap reference for these devices has low noise and long-term stability.
