DESCRIPTION The VRG8609/10 consists of two negative (RH137) voltage regulators each capable of supplying in excess of 1.5Amps over the output voltage range as defined under recommended operating conditions. Each regulator is exceptionally easy to set-up, requiring only 2 external resistors to set the output voltage. The module design has been optimized for excellent regulation and low thermal transients. There is full electrical isolation between the regulators and each regulator to the package. Further, the VRG8609/10 features internal current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads. The VRG8609/10 serves a wide variety of applications including local on-card regulation, programmable output voltage regulation or precision current regulation. The VRG8609/10 has been specifically designed to meet exposure to radiation environments. The VRG8609 is configured for a Thru-Hole 6 lead metal power package and the VRG8610 is configured for a Surface Mount 6 lead metal power package. It is guaranteed operational from -55°C to +125°C. Available screened to MIL-STD-883, the VRG8609/10 is ideal for demanding military and space applications. For detailed performance characteristic curves, applications information and typical applications see the latest Linear Technology Corporation ® data sheets for their RH/LT137, which is available on-line at www.linear.com. 14 ADJ ADJ 2 VOUT VOUT 6 RH137 Negative Regulator RH137 Negative Regulator VIN VIN SCD8609 Rev F 35 FIGURE 1 – BLOCK DIAGRAM / SCHEMATIC 1 Cobham Semiconductor Solutions www.cobham.com/HiRel ABSOLUTE MAXIMUM RATINGS PARAMETER Operating (Junction) Temperature Range Lead Temperature (soldering, 10 sec) Storage Temperature Range Input-Output Voltage Differential Thermal Resistance (junction to case JC) each, Pos. & Neg.
