SG1503/SG2503/SG3503
PRECISION 2.5-VOLT REFERENCE
DESCRIPTION
FEATURES
• Output voltage trimmed to ±1%
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.
• Input voltage range of 4.5 to 40V
• Temperature coefficent of 10ppm/°C
• Quiescent current typically 1.5mA
• Output current in excess of 10mA
• Interchangeable with MC1503 and AD580
HIGH RELIABILITY FEATURES - SG1503
♦ Available to MIL-STD-883 and DESC SMD
♦ Radiation data available
♦ LMI level "S" processing available
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
T Package:
Note A. Junction Temperature Calculation: TJ = T + (PD x θJA).
Note B. The above numbers for θJC are maximuAms 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.

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.)
