To calculate a reliability number according to MIL-HDBK-217 for the TPS82150 I have assumed that it falls into the "MOS Technology" "Linear Microcircuits" Technology. I would need the range of the number of transistors. I have not been able to find it anywhere in the documentation.
The possible ranges are:
1 to 100 transistors
101 to 303 transistors
301 to 1000 transistors
1001 to 10.000 transistors
