SCD8601 Rev T

DESCRIPTION

The Aeroflex Plainview VGR8601/02 consists of a positive (RH117) and a negative (RH137) voltage regulator 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 positive and negative regulators and each regulator to the package.

Further, the VRG8601/ 02 features internal current limiting, thermal shutdown and safe-area compensation, making

them virtually blowout-proof against overloads. The VRG8601/02 serves a wide variety of applications including

local on-card regulation, programmable output voltage regulation or precision current regulation.

The VRG8601/02 has been specifically designed to meet exposure to radiation environments. The VRG8601 is

configured for a Thru-Hole 6 lead metal power package and the VRG8602 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

VRG8601/ 02 is ideal for demanding military and space applications.
