(1) Frequency of transient load current ranges from 0 to 1 MHz with duty cycle of 50%. For cases where duty cycle and frequency are limited by tr and tf, the highest frequency is set by 1 / (tr + tf), where tr is rise time (0% to 100%) and tf is fall time (100% to 0%).
(2) Additional overshoot of up to 100 mV is allowed as long as it lasts less than 50 µs.
