SG117A/SG117
1.5A Three Terminal Adjustable Voltage Regulator
Features
Description
Adjustable Output Down to 1.25V
The SG117 and SG117A are 3-terminal positive
adjus table voltage regulators which offer improved
1% Output Voltage Tolerance
performance over the original 117 design. A major
0.01%/V Line Regulation
feature of the SG117A is a reference voltage tolerance
0.3% Load Regulation
guaranteed within 1%, allowing an overall power
Min. 1.5A Output Current
supply tolerance to be better than 3% using
inexpensive 1% resistors. Line and load regulation Typical 80dB Ripple Rejection
performance has been improved as well.
Available in Hermetic TO-257
Moreover, the SG117A reference voltage is guaranteed
not to exceed 2% when operating over the full load, line

and power dissipation conditions. The SG117A
SG117A/SG117
adjustable regulators offer an improved solution for all
Available to MIL-STD-883, 1.2.1
positive voltage regulator requirements with load
currents up to 1.5A. MSC-AMS level Processing Available
In addition to replacing many fixed regulators, the Available to DSCC
SG117/A can be used in a variety of other applications
Standard Microcircuit Drawing (SMD)
due to its floating design as long as the input-to-output
MIL-M-38510/7703405XA SG117AT-JAN
differential maximum is not exceeded, such as a
MIL-M-38510/7703405YA SG117AK-JAN
current source. A higher voltage version is available
the SG117AHV and SG117HV which offers input
voltage up to 60V.
