RECOMMENDED OPERATING CONDITIONS (Note 3) ELECTRICAL CHARACTERISTICS (Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1544 with -55 °C ≤ T A ≤ 125°C, SG2544 with -25 °C ≤ T A ≤ 85°C, SG3544 with 0°C ≤ TA ≤ 70°C, and +VIN = 10V. Indicator outputs have 2kΩ pull-up resistors. All electrical ratings and specifications are tested with the inverting over-voltage input and the non-inverting under-voltage input externally connected to the 2.5V reference. Low duty cycle testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.) 7 40 40 10 4.5 4.7 Supply Section T J = 25°C to TMAX +V IN = 40V, Outputs open Input Voltage Range Supply Current SG3544 SG1544/2544 Units Test Conditions Parameter 2.50 1 1 25 .005 2.48 2.45 12 Reference Section T J = 25°C +V IN = 5 to 30V I REF = 0 to 10mA V REF = 0V Output Voltage Line Regulation Load Regulation Short Circuit Current Temperature Stability V V mV mV mA %/ °C V V mA 40 40 10 7 4.5 4.7 Min.

The above numbers for θ JC are maximums for the limiting thermal resistance of the package in a standard mount- ing configuration. The θ JA numbers are meant to be guidelines for the thermal performance of the device/pc- board system. All of the above assume no ambient airflow.
