DESCRIPTION

The Aeroflex Plainview VRG8651/8652 consists of one Positive Adjustable (RH1086) and one Negative Adjustable

(RH1185) LDO voltage regulator capable of supplying 1.0Amps (RH1086) /3Amps(RH1185) respectively over the

output voltage range as defined under recommended operating conditions. The VRG8651/8652 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 VRG8651/8652 serves a wide variety of applications including SCSI-2 Active Terminator, High Efficiency

Linear Regulators, Post Regulators for Switching Supplies, Constant Current Regulators, Battery Chargers and

Microprocessor Supply.

The VRG8651/8652 has been specifically designed to meet exposure to radiation environments. The VRG8651 is

configured for a Thru-Hole 8 lead metal power package and the VRG8652 is configured for a Surface Mount 8 lead

metal power package. It is guaranteed operational from -55°C to +125°C. Available screened to MIL-STD-883, the

VRG8651/8652 is ideal for demanding military and space applications.
