SG117AT中文资料

DESCRIPTIONThe SG117A Series are 3-terminal positive adjustable voltageregulators which offer improved performance over the original 117design. A major feature of the SG117A is reference voltagetolerance guaranteed within ± 1%, allowing an overall power supplytolerance to be better than 3% using inexpensive 1% resistors. Lineand load regulation performance has been improved as well.Additionally, the SG117A reference voltage is guaranteed not toexceed 2% when operating over the full load, line and powerdissipation conditions. The SG117A adjustable regulators offer animproved solution for all positive voltage regulator requirementswith load currents up to 1.5A.FEATURES•1% output voltage tolerance

ELECTRICAL CHARACTERISTICS(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG117A/SG117 with -55°C ≤ TA ≤ 125°C, SG217A/SG217 with -25°C ≤ TA ≤ 150°C, SG 317A/SG317 with 0°C ≤ TA ≤ 125°C, VIN - VOUT = 5.0V , and for IOUT = 500mA (K, R, and IG), and IOUT = 100mA(T and L packages). Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the T and Lpackages, and 20W for the K, R, and IG packages. IMAX is 1.5A for the K, R, and IG packages and 500mA for the T and L packages. Low duty cycle

pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
