DESCRIPTION

The Aeroflex Plainview VRG8697/8698 consists of two Positive Adjustable (RH3083) ULDO voltage

regulators each capable of supplying 2.5Amps over the output voltage range as defined under

recommended operating conditions. The VRG8697/8698 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 VRG8697/8698 has been specifically designed to meet exposure to radiation environments. The

VRG8697 is configured for a Thru-Hole 8 lead metal power package and the VRG8698 is configured for a

Surface Mount 8 lead metal power package. It is guaranteed operational with a case operating temperature

from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534, the VRG8697/8698 is

ideal for demanding military and space applications.

Dropout (VIN - VOUT) decreases at lower load currents for both regulators.

FIGURE 2 – MAXIMUM POWER vs CASE TEMPERATURE

The maximum Power dissipation is limited by the thermal shutdown function of each regulator chip in the

VRG8697/8698. 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 VRG8697/8698 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 VRG8697/8698 will fall between the

two lines. This graph is based on the maximum junction temperature of 150°C and a thermal resistance (JC) of

4°C/W.
