Unless otherwise specified, VIN=5.0V, R1=1.62K, VSHUTDOWN=0V and IOUT=10mA. See Figure 2.

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 requested.

Military grade devices ("H" suffix) shall be 100% tested to subgroups 1,2,3 and 4.

Subgroup 5 and 6 testing available upon request.

TC=+25°C

Subgroup 2,5

TC=+125°C

Subgroup 3,6

TA=-55°C

Output current limit is dependent upon the values of VIN and VOUT. See Figure 1 and typical performance curves.

Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.

VIN shall be as specified or VIN Min, whichever is greater.

Not applicable when VOUT<VIN Min - dropout voltage maximum.

Consult factory for post radiation limits.
