WU UPACKAGE/ORDER I FOR ATIOBUR -I CIRCUITU U BOTTOM VIEW ADJ VOUT VIN CASE IS INPUT H PACKAGE 3-LEAD TO-39 METAL CAN VOUT CASE IS VIN ADJ K PACKAGE 2-LEAD TO-3 METAL CAN (STEEL) BOTTOM VIEW The RH137 negative adjustable regulator will deliver up to 1.5A output current over an output voltage range of –1.2V to –32V. Every effort has been 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. Maximum reliability is attained with Linear Technology’s advanced processing techniques combined with a 100% burn-in in the thermal limit mode. This assures that all device protection circuits are working and eliminates field failures experienced with other regulators that receive only standard electrical testing. The wafer lots are processed to Linear Technology’s in- house Class S flow to yield circuits usable in stringent military applications.

Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the TO-39 and 20W for the TO-3. I MAX is 0.2A for the TO-39 and 1.5A for the TO-3 package. Note 2: Regulation is measured at a constant junction temperature using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specification for thermal regulation. Note 3: Guaranteed by design, characterization or correlation to other tested parameters.

MIL-STD-883 TEST REQUIREMENTS SUBGROUP Final Electrical Test Requirements (Method 5004) 1*,2,3 Group A Test Requirements (Method 5005) 1,2,3 Group C and D End Point Electrical Parameters 1 (Method 5005) * PDA Applies to subgroup 1. See PDA Test Notes. PDA Test Notes The PDA is specified as 5% based on failures from group A, subgroup 1, tests after cooldown as the final electrical test in accordance with method 5004 of MIL-STD-883 Class B. The verified failures of group A, subgroup 1, after burn-in divided by the total number of devices submitted for burn- in in that lot shall be used to determine the percent for the lot. Linear Technology Corporation reserves the right to test to tighter limits than those given.
