SG117AIG
Description
1.5 A 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.
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.
