DESCRIPTION
The VRG8667/8668 consists of two Positive Adjustable (RH3080) ULDO voltage regulators each capable of
supplying 1.0Amps over the output voltage range as defined under recommended operating conditions. The
VRG8667/8668 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 VRG8667/8668 has been specifically designed to meet exposure to radiation environments. The VRG8667 is
configured for a Thru-Hole 8 lead metal power package and the VRG8668 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 VRG8667/8668 is ideal for demanding military and space applications.
Dropout (VIN - VOUT) decreases at lower load currents for both regulators.
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
