DESCRIPTION
The Aeroflex Plainview VRG8667/8668 consists of two Positive Adjustable (RH3080) ULDO voltage
regulators each capable of supplying 1.0Amps over the output voltage range as defined under recommended operating conditions. The VRG8667/8668 offers excellent line and load regulation specifications and ripple rejection. There is full electrical isolation between the
regulators and each
regulator to the package.
The VRG8667/8668 has been specifically designed to meet exposure to radiation environments. The VRG8...
