DESCRIPTION
This monolithic integrated circuit is a fully self-contained precision voltage
reference generator, internally trimmed for ±1% accuracy. Requiring less
than 2mA in quiescent current, this device can deliver in excess of 10mA
with total load- and line-induced tolerances of less than 0.5%. In additon
to voltage accuracy, internal trimming achieves a temperature coefficient
of output voltage of typically 10 ppm/°C. As a result, these references are
excellent choices for application to critical instrumentation and D-to-A
converter systems.
The SG1503 is specified for operation over the full military ambient
temperature range of -55°C to 125°C , while the SG2503 is designed for
-25°C to 85°C and the SG3503 for commercial applications of 0°C to 70°C.

THERMAL DATA
Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA).
Note B. The above numbers for θJC are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The θJA numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.

RECOMMENDED OPERATING CONDITIONS (Note 2)
ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1503 with -55°C ≤ TA ≤ 125°C, SG2503/SG3503
with 0°C ≤ TA ≤ 70°C, VIN = 15V, and IL = 0mA. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal
to the ambient temperature.)
