Description
The SG117 and SG117A are 3-terminal positive
adjustable voltage regulators which offer improved
performance over the original 117 design. A major
feature of the SG117A is a reference voltage tolerance
guaranteed within ± 1%, allowing an overall power
supply tolerance to be better than 3% using
inexpensive 1% resistors. Line and load regulation
performance has been improved as well.
Moreover, the SG117A reference voltage is guaranteed
not to exceed 2% when operating over the full load, line
and power dissipation conditions.
The SG117A
adjustable regulators offer an improved solution for all
positive voltage regulator requirements with load
currents up to 1.5A.
In addition to replacing many fixed regulators, the
SG117/A can be used in a variety of other applications
due to its ‘floating’ design as long as the input-to-output
differential maximum is not exceeded, such as a
current source. A higher voltage version is available
the SG117AHV and SG117HV which offers input
voltage up to 60V.
