DESCRIPTION
The VRG8684 consists of a Positive Adjustable (RH1084) LDO voltage regulator capable of supplying 3.0
Amps 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.
Dropout (VIN - VOUT) decreases at lower load currents.
