1.5A Three Terminal Adj. Voltage Regulator

ELECTRICAL CHA RACTERISTICS (CONTINUED)

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 K, R, G, and IG packages. IMAX is

1.5A for the K, R, G, and IG packages and 500m for the T, F, and L packages. Low duty cycle pulse testing techniques are used which

maintains junction and case temperatures equal to the ambient temperature.
