DESCRIPTION
The VRG8607/08 consists of two positive (RH117) voltage regulators each capable of supplying in excess of
1.5Amps over the output voltage range as defined under recommended operating conditions. Each regulator is
exceptionally easy to set-up, requiring only 2 external resistors to set the output voltage. The module design has been
optimized for excellent regulation and low thermal transients. There is full electrical isolation between the regulators
and each regulator to the package.
Further, the VRG8607/08 features internal current limiting, thermal shutdown and safe-area compensation, making
them virtually blowout-proof against overloads. The VRG8607/08 serves a wide variety of applications including
local on-card regulation, programmable output voltage regulation or precision current regulation.
The VRG8607/08 has been specifically designed to meet exposure to radiation environments. The VRG8607 is
configured for a Thru-Hole 6 lead metal power package and the VRG8608 is configured for a Surface Mount 6 lead
metal power package. It is guaranteed operational from -55°C to +125°C. Available screened to MIL-STD-883, the
VRG8607/08 is ideal for demanding military and space applications.
For detailed performance characteristic curves, applications information and typical applications see the
Linear Technology Corporation ® data sheets for their RH/LT117, which is available on-line at

heating effects are covered under the specification for thermal regulation. Measurements taken at the output lead must be adjusted for
lead resistance.

FIGURE 2 – MAXIMUM POWER vs CASE TEMPERATURE
The maximum Power dissipation is limited by the thermal shutdown function of each regulator chip in the VRG8607/08. The
graph above represents the achievable power before the chip shuts down. The first line in the graph represents the maximum
power dissipation of the VRG8607/08 with one regulator on (the other off) and the other line represents both regulators on
dissipating equal power. If both regulators are on and one regulator is dissipating more power that the other, the maximum power
dissipation of the VRG8607/08 will fall between the two lines. This graph is based on the maximum junction temperature of
150°C and a thermal resistance (JC) of 5°C/W.
