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.
