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 ext ernal resistors to set the output vo ltage .
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/ 0 2 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, programmab le 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.
For detailed performance characteristic curves, applications information and typical applications see the
latest Linear Technology Corporation ®data sheets for their RH/LT117 and RH/LT137, which is available
