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.
