DESCRIPTION
The Aeroflex Plainview VGR8601/02 consists of a positive (RH117) and a negative (RH137) voltage regulator 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 positive and negative regulators and each regulator to the package.
Further, the VRG8601/ 02 features internal current limiting, thermal shutdown and safe-area compensation, making
them virtually blowout-proof against overloads. The VRG8601/02 serves a wide variety of applications including
local on-card regulation, programmable output voltage regulation or precision current regulation.
The VRG8601/02 has been specifically designed to meet exposure to radiation environments. The VRG8601 is
configured for a Thru-Hole 6 lead metal power package and the VRG8602 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/ 02 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 VRG8601/02. 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 VRG8601/02 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 VRG8601/02 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.
