LT1389 - Nanopower Precision Shunt Voltage Reference
The LT1389 is a nanopower, precision shunt voltage reference. The bandgap reference uses trimmed precision thin-film resistors and improved curvature correction techniques to achieve 0.05% initial voltage accuracy with guaranteed 10ppm/°C maximum temperature drift. Voltage regulation is maintained to an ultralow 800nA operating current. Advances in design, processing and packaging achieve low temperature cycling hysteresis. The LT1389 does not require an output compensation capacitor, but is stable with capacitive loads. Low dynamic impedance makes the LT1389 reference easy to use from unregulated supplies.The LT1389 reference can be used as a high performance upgrade to the LM185/LM385, LT1004, LT1034 and LT1634 where lowest power and guaranteed temperature drift are required.
