NOTES:
1 +VIN = 28V, IOUT = 417mA, TA=TC=25°C unless otherwise specified.
2 Guaranteed by design but not tested. Typical parameters are representative of actual device performance but are for reference only.
3 Industrial grade and "E" suffix devices shall be tested to subgroups 1 and 4 unless otherwise specified.
4 Military grade devices ("H" suffix) shall be 100% tested to subgroups 1, 2, 3 and 4.
5 Subgroups 5 and 6 testing available upon request.
6 Subgroup 1, 4 TA=TC=+25°C
2, 5 TA=TC=+125°C
3, 6 TA=TC= -55°C
7 Device has internal shutdown feature that pulses the output with a low duty cycle during faults.
8 Consult DSCC SMD for electrical parameters for devices purchased as such.
