6.4 Electrical Characteristics (continued)

over recommended operating junction temperature range, VI(IN) = 5.5 V, IO = 1 A, VI( ENx) = 0 V, or VI(ENx) = 5.5 V (unless

otherwise noted)

(1)

Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account

separately.

(2)

TPS2061, TSP2062, TPS2065, and TPS2066 do not have overcurrent trip threshold. Current is limited to IOS under different test

condition. Check Section 8.7 for more details.

(3)

The thermal shutdown only reacts under overcurrent conditions.
