NOTES:
1 Unless otherwise specified, VIN=5.0V, R1=1.62K, VSHUTDOWN=0V and IOUT=10mA. See Figure 2.
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 requested.
4 Military grade devices ("H" suffix) shall be 100% tested to subgroups 1,2,3 and 4.
5 Subgroup 5 and 6 testing available upon request.
6 Subgroup 1,4 TC=+25°C
Subgroup 2,5 TC=+125°C
Subgroup 3,6 TA= 55°C
7 Output current limit is dependent upon the values of VIN and VOUT. See Figure 1 and typical performance curves.
8 Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.
9 VIN shall be as specified or VIN Min, whichever is greater.
10 Not applicable when VOUT<VIN Min dropout voltage maximum.
11 Consult factory for post radiation limits.
