DESCRIPTION
The Aeroflex Plainview VRG8667/8668 consists of two Positive Adjustable (RH3080) ULDO voltage
regulators each capable of supplying 1.0Amps over the output voltage range as defined under
recommended operating conditions. The VRG8667/8668 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 VRG8667/8668 has been specifically designed to meet exposure to radiation environments. The
VRG8667 is configured for a Thru-Hole 8 lead metal power package and the VRG8668 is configured for a
Surface Mount 8 lead metal power package. It is guaranteed operational from -55°C to +125°C. Available
screened in accordance with MIL-PRF-38534, the VRG8667/8668 is ideal for demanding military and
space applications.
Dropout (VIN - VOUT) decreases at lower load currents for both regulators.
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.

FIGURE 2 – MAXIMUM POWER vs CASE TEMPERATURE
The maximum Power dissipation is limited by the thermal shutdown function of each regulator chip in the
VRG8667/8668. The graph above represents the achievable power before the chip shuts down. The first line in the
graph represents the maximum power dissipation of the VRG8667/8668 with one regulator on (the other off) and
the other line represents both regulators on, dissipating equal power. If both regulators are on and one regulator is
dissipating more power than the other, the maximum power dissipating of the VRG8667/8668 will fall between the
two lines. This graph is based on the maximum junction temperature of 150°C and a thermal resistance (JC) of
7°C/W.
