DESCRIPTION

The Aeroflex Plainview VRG8684 consists of a Positive Adjustable (RH1084) LDO voltage regulator capable of

supplying 3.0Amps over the output voltage range as defined under recommended operating conditions. The VRG8684

offers excellent line and load regulation specifications and ripple rejection.

The VRG8684 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 VRG8684 has been specifically designed to meet exposure to radiation environments and is configured for a

SMD-0.5 SMT power package. It is guaranteed operational from -55°C to +125°C. Available screened in accordance

with MIL-PRF-38534, the VRG8684 is ideal for demanding military and space applications.
