SGR117A
ADVANCED DATA SHEET
RAD HARD 1.5 AMP THREE TERMINAL
ADJUSTABLE VOLTAGE REGULATOR
DESCRIPTION
The RAD HARD SGR117A 3-terminal positive adjustable
regulators have been designed to meet the most stringent
space and strategic level radiation requirements while meeting
the industry standard LM117A and LM117 electrical
specifications.
In addition to the features of the standard SGR117A, these
devices are capable of meeting the attached data sheet
electricals after the following radiation events:

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SGR117 with -55°C ≤ TA ≤ 125°C, VIN - V
5.0V, and for I
for power dissipations of 2W for the T package, and 20W for the K and IG packages. I
Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
