DESCRIPTION
The 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, ...
