DESCRIPTION

The Aeroflex Plainview VRG8657/8658 consists of two Positive Adjustable (RH1086) LDO voltage regulators each

capable of supplying 1.0Amps over the output voltage range as defined under recommended operating conditions. The

VRG8657/8658 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 VRG8657/8658 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 VRG8657/8658 has been specifically designed to meet exposure to radiation environments. The VRG8657 is

configured for a Thru-Hole 6 lead metal power package and the VRG8658 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

VRG8657/8658 is ideal for demanding military and space applications.

Dropout (VIN - VOUT) decreases at lower load currents for both regulators.
