DESCRIPTION
The Aeroflex Plainview 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.
