The LT
®
1389 is a nanopower, precision shunt voltage
reference. The bandgap reference uses trimmed preci-
sion thin-film resistors and improved curvature correction
techniques to achieve 0.05% initial voltage accuracy with
guaranteed 10ppm/°C maximum temperature drift. Volt-
age 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 dy-
namic 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 tempera-
ture drift are required.
