| SGR137 / SGR137A Amp Negative Adjustable Regulator The SGR137/SGR137A is fit, form and function compatible to the SG137/SG137A with the addition of guaranteed performance after radiation exposure to Total Ionizing Dose TID , Enhanced Low Dose Rate Sensitivity ELDRS , and Single Event Latch-up SEL conditions. The SGR137A family of negative adjustable regulators deliver up to 1.5A output current over an output voltage range of -1.2V to -37V. The device includes significant improvements, such as better line and load regulation, and a maximum output voltage error of The SGR137 family uses the same chip design and guarantees maximum output voltage error of Every effort is made to make these devices easy to use and difficult to damage. Internal current and power limiting coupled with true thermal limiting prevents device damage due to overloads or shorts even if the regulator is not fastened to a heat sink. The SGR137/SGR137A family of products are ideal complements to the SGR117A/117 adjustable positive voltage regulators. • 1% Output Voltage Tolerance • 0.01%/V Line Regulation • Load Regulation • 0.02%/W Thermal Regulation • Available in Hermetic TO-220 High Reliability Features SGR137/SGR137A • Rad-tolerance Test data available • TID to a Minimum of 50krad Si • ELDRS to a Minimum of 50krad Si • SEL Immunity to a Minimum of 87MeV-cm2/mg + C2 5 µF SOLID TANTALUM R1 121W + C3 1 µF SOLID TANTALUM -VIN SGR137A VOUT -VOUT = V 1+R2/R1 *R2 = Figure 1 • Typical Application 2014 Microsemi Corporation- Analog Mixed Signal Group Amp Negative Adjustable Regulator OUTPUT VOLTAGE ERROR % 9 2% RESISTORS SGR137 1% RESISTORS 6 2% RESISTORS 5 SGR137A 1% RESISTORS OUTPUT VOLTAGE Figure 2 • Resistor Precision vs. Output Voltage Error Connection Diagrams and Ordering Information Ambient Type Temperature Package Packaging Type Connection Diagram SGR137AK -55°C to 3-Terminal SGR137AK-EV* 125°C Metal Can TO-3 SGR137K SGR137K-EV* VOUT CASE IS VIN SGR137AT -55°C to 125°C 3-Terminal Metal Can SGR137AT-EV* TO-39 SGR137T SGR137T-EV* ADJ 1 2 VOUT 3 VIN CASE IS VIN SGR137AIG SGR137AIG-EV* -55°C to IG 3-Pin Hermetic TO-257 VOUT 125°C To-257 SGR137IG Isolated SGR137IG-EV* * EV is Microsemi’s “Equivalent V” flow that follows MIL-PRF-38535 requirements for Class V processing.
