Note A. Junction Temperature Calculation: T

J = TA + (PD x θJA).

Note B. The above numbers for

JC are maximums for the limiting

thermal resistance of the package in a standard mount-

ing configuration. The

JA numbers are meant to be

guidelines for the thermal performance of the device/pc-

board system. All of the above assume no ambient

airflow.

ELECTRICAL CHARACTERISTICS

(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SGR117 with -55°C

≤ T

A ≤

125°C, V

- V

OUT

5.0V, and for I

OUT = 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. I

MAX 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 temperature.)
