SG117 / 217 / 317 / 117A / 217A / 317A
TM ® 1.5A Three Terminal Adj. Voltage Regulator
DESCRIPTION
The SG117A Series are 3-terminal Additionally, the SG117A reference positive adjustable voltage regulators voltage is guaranteed not to exceed 2% which offer improved performance when operating over the full load, line over the original 117 design. A major and power dissipation conditions. The feature of the SG117A is reference SG117A adjustable regulators offer an voltage tolerance guaranteed within ± improved solution for all positive 1%, allowing an overall power supply voltage regulator requirements with tolerance to be better than 3% using load currents up to 1.5A. inexpensive 1% resistors. Line and load regulation performance has been improved as well.

ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications apply over the full operating ambient temperature for the SG117A / SG117 with -55°C < TA < 125°C, the SG217A / SG217 with -25°C < TA < 85°C, and the SG317A / SG317 with 0°C < TA < 70°C, VIN – VOUT = 5.0V and for IOUT = 500mA (K,R, G, and IG) and IOUT = 100mA (T, F, and L packages). Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the T and L packages, and 20W for the .
