Notes
a. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
b. These ratings vary with PCB layout and operating condition, and limited by SPS temperature and thermal shutdown trip point.
c. Limits apply across the operating temperature range.
