Operating currents are guaranteed from as low as 15µA up to 20mA for the LM385/385B-1.2, and 20µA up to 20mA for the LM385/385B-2.5, giving designers a great deal of flexibility in optimizing power consumption, noise and ultimate application performance. As an added feature, the references output impedance is extraordinarily low over the entire operating range of quiescent currents. This enables an extremely wide dynamic load range with little effect on the overall reference accuracy. The LM385 family is available in fixed 1.2V and 2.5V reference values. Process and circuit design optimization provide for high accuracy with i...
