Note:

1. Maximum package power dissipation must be observed.

2. Maximum power dissipation for the SOT223 and SO8 packages is calculated assuming that

the device is mounted on a PCB measuring 2 inches square.

3. Low duty cycle pulse techniques are used during test to maintain junction temperatures as

close to ambient as possible

4. A time delayed reset can be accomplished with the additional Cd.

5. Operation above Vz may be restricted by the supply current rating Iz
