DESCRIPTION The Aeroflex Plainview VRG8607/08 consists of two positive (RH117) 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 VRG8607/08 features internal current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads. The VRG8607/08 serves a wide variety of applications including local on-card regulation, programmable output voltage regulation or precision current regulation. The VRG8607/08 has been specifically designed to meet exposure to radiation environments. The VRG8607 is configured for a Thru-Hole 6 lead metal power package and the VRG8608 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 VRG8607/08 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/LT117, which is available on-line at www.linear.com. 14 ADJ ADJ 2 VOUT VOUT 6 RH117 Positive Regulator RH117 Positive Regulator VIN VIN 3 SCD8607 Rev E FIGURE 1 – BLOCK DIAGRAM / SCHEMATIC 5 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 Regulator ESD Rating RANGE -55 to +150 300 -65 to +150 40 (Pos) 5 1.999 1/ UNITS C °C C V °C/W KV 1/ Meets ESD testing per MIL-STD-883, method 3015, Class 1C.
