Notes:
1. Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device. Measured on approximately
1” square of 1oz copper.
2. The PS22924 is guaranteed to meet performance specifications over the -40°C to +125°C junction operating temperature range and
is assured by design, characterization, and correlation with statistical process control.
3. Load regulation is measured using pulse techniques with duty cycle <5%.
