+VIN = 28V, IOUT = 1.8A for DHC2803S, IOUT = 1.0A for DHC2805S, TA=TC=25°C unless otherwise specified.
Guaranteed by design but not tested. Typical parameters are representative of actual device performance but are for reference only.
Industrial grade and "E" suffix devices shall be tested to subgroups 1 and 4 unless otherwise specified.
Military grade devices ("H" suffix) shall be 100% tested to subgroups 1, 2, 3 and 4.
Subgroups 5 and 6 testing available upon request.
Subgroup 1, 4 TA=TC=+25°C
2, 5 TA=TC=+125°C
3, 6 TA=TC= -55°C
Device has internal shutdown feature that pulses the output with a low duty cycle during faults.
Refer to DSCC SMD for electrical specifications for devices purchased as such.
