General Description
Aeroflex's ACT8600 is a radiation hardened, Dual adjustable 6-terminal device containing a
positive (LM117) and a negative (LM137) voltage regulator each capable of supplying in excess of
1.5A over an output voltage range of 1.2V to 37V. 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 ACT8600 features internal current limiting, thermal shutdown and safe-area
compensation, making them virtually blowout-proof against overloads. The ACT8600 serves a
wide variety of applications including local on-card regulation, programmable output voltage
regulation or precision current regulation.
The ACT8600 has been specifically designed to meet exposure to radiation environments. It is
available in a 6 lead Metal Power Package. It is guaranteed operational from -55C to +125C.
Available screened to MIL-STD-883, the ACT8600 is ideal for demanding industrial, military and
space applications.

Notes:
1/ 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. With exception of cases U and 2, all output measurements are referenced
to the case. Measurements taken at the output lead must be adjusted for lead resistance.
2/ If not tested, shall be guaranteed to the specified limits.
