DESCRIPTION The Aeroflex Plainview VRG8653/54 consists of one Positive Adjustable (RH1084) and one Negative Adjustable (RH1185) LDO voltage regulator, both capable of supplying 3.0Aover the output voltage range as defined under recommended operating conditions. The VRG8653/54 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 VRG8653/54 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 VRG8653/54 has been specifically designed to meet exposure to radiation environments and is configured for a Thru-Hole 8 lead metal power package and the VRG8654 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 VRG8653/54 is ideal for demanding military and space applications. Dropout (VIN - VOUT) decreases at lower load currents for both regulators.
