ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SGR117 with -55°C ≤ TA ≤ 125°C, VIN - VOUT =
5.0V, and for IOUT = 500mA (K and IG), and IOUT = 100mA (T package). Although power dissipation is internally limited, these specifications are applicable
for power dissipations of 2W for the T package, and 20W for the K and IG packages. IMAX is 1.5A for the K and IG packages and 500mA for the T package.
Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperatur e.)
