DESCRIPTION
The positive (RH117) and a negative (RH137) voltage regulator are 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 positive and negative
regulators and each to the package.
Further, the VRG8601/ 2/ 3/ 4 features internal current limiting, thermal shutdown and safe-area compensation,
making them virtually blowout-proof against overloads. The VRG8601/ 2/ 3/ 4 serves a wide variety of applications
including local on-card regulation, programmable output voltage regulation or precision current regulation.
The VRG8601/ 2/ 3/ 4 has been specifically designed to meet exposure to radiation environments. The VRG8601/ 3 is
configured for a Thru-Hole 6 lead metal power package and the VRG860 2/ 4 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
VRG8601/ 2/ 3/ 4 is ideal for demanding military and space applications.

Notes:
1. Unless otherwise specified, these specifications apply for post radiation, (Vin - Vout) = 5V, Iout = 0.5A and -55°C < Tc < +125°C.
2. Regulation is measured at a constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to
heating effects are covered under the specification for thermal regulation. Measurements taken at the output lead must be adjusted for lead
resistance.
3. Not tested. Shall be guaranteed to the specified limits.

The maximum Power dissipation is limited by the thermal shutdown function of each regulator chip in the VRG860X. 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 VRG860X 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 VRG860X will fall between the two lines. This graph is based on the maximum junction temperature of 150°C and a
thermal resistance (
Θ
JC
) of 5°C/W.
