LM385B-2.5

微功耗电压基准 MICROPOWER VOLTAGE REFERENCES

description

These micropower two-terminal band-gap voltage references operate over a 20-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.
