DESCRIPTION  
The Aeroflex Plainview VRG8687/8688 consists of two Positive Adjustable (RH1084) LDO voltage regulators each  
capable of supplying 3.0Amps over the output voltage range as defined under recommended operating conditions. The  
VRG8687/8688 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 VRG8687/8688 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 VRG8687/8688 has been specifically designed to meet exposure to radiation environments. The VRG8687 is  
configured for a Thru-Hole 8 lead metal power package and the VRG8688 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 VRG8687/8688 is ideal for demanding military and space applications.  
Dropout (VIN - VOUT) decreases at lower load currents for both regulators.
