Electrical Performance Characteristics - Notes
1. Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall be
guaranteed to the limits specified.
2. Parameter verified during line and load regulation tests.
3. Guaranteed for a D.C. to 20MHz bandwidth. Tested using a 20KHz to 10MHz bandwidth.
4. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance.
A capacitive load in excess of the maximum limit may cause erratic behavior during turn-on.
5. Overload power dissipation is defined as the device power dissipation with the load set such that VOUT = 90% of
nominal.
6. Load step transition time ≤ 1.0 µs/A for 3.3V & 2.5V models and ≤ 0.1 µs/A for 1.0V, 1.2V, 1.5V & 1.8V models.
7. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of its
steady state value.
8. Line step transition time ≤ 10 µs.
9. Turn-on delay time from either a step application of input power or a logic low to a logic high transition on the
Enable pin (pin 10) to the point where VOUT = 90% of nominal.
