NOTES:
2. For all values in this table, the device is connected as shown in Figure 1 with the divider resistance as seen by the error amplifier
≤
10 k
. Unless otherwise specified, VI = VCC+ = VC = 12 V, VCC– = 0, VO = 5 V, IO = 1 mA, RSC = 0, and Cref = 0.
3. Pulse-testing techniques must be used that will maintain the junction temperature as close to the ambient temperature as possible.
