DESCRIPTION
The Aeroflex Plainview VRG8666 consists of a Positive Adjustable (RH3080) ULDO voltage regulator
capable of supplying 1.0Amps over the output voltage range as defined under recommended operating
conditions. The VRG8666 offers excellent line and load regulation specifications and ripple rejection.
The VRG8666 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 VRG8666 has been specifically designed to meet exposure to radiation environments and is configured
for an SMD power package. It is guaranteed operational from -55°C to +125°C. Available screened to
MIL-STD-883, the VRG8666 is ideal for demanding military and space applications.
Dropout (VIN - VOUT) decreases at lower load currents.
For detailed performance characteristic curves, applications information and typical applications see the
latest
Linear Technology Corporation ® data sheets for their RH/LT3080, which is available
on-line at www.linear.com.
