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.

Input capacitance is required for load regulation. 1uF is recommended on Vin and Vcontrol. For stable

operation, a 0.1uF capacitor should be placed on Vset and a low ESR capacitor on Vout. See Figure 5.

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 the regulator chip in the VRG8666.

The graph above represents the achievable power before the chip shuts down. The line in the graph represents the

maximum power dissipation of the VRG8666 This graph is based on the maximum junction temperature of 150°C

and a thermal resistance (JC) of 5°C/W.
