SG117A/SG217A/SG317A
SG117/SG217/SG317
1.5 AMP THREE TERMINAL
ADJUSTABLE VOLTAGE REGULATOR
DESCRIPTION
The SG117A Series are 3-terminal positive adjustable voltage
regulators which offer improved performance over the original 117
design. A major feature of the SG117A is 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.
Additionally, 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.

Note 4. Regulation is measured at 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.
