DESCRIPTION

The Aeroflex Plainview VRG8697/8698 consists of two Positive Adjustable (RH3083) ULDO voltage

regulators each capable of supplying 2.5Amps over the output voltage range as defined under

recommended operating conditions. The VRG8697/8698 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 VRG8697/8698 has been specifically designed to meet exposure to radiation environments. The

VRG8697 is configured for a Thru-Hole 8 lead metal power package and the VRG8698 is configured for a

Surface Mount 8 lead metal power package. It is guaranteed operational with a case operating temperature

from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534, the VRG8697/8698 is

ideal for demanding military and space applications.
