ATW28XXS Series
Table II. Electrical Performance Characteristics - continued
Notes to Specifications
ATW2812S
1
Parameter guaranteed by line and load regulation tests.
2
Bandwidth guaranteed by design. Tested for 20kHz to 2.0MHz.
3
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 will not disturb loop stability but may interfere with the
operation of the load fault detection circuitry, appearing as a short circuit during turn-on.
4
Parameter shall be tested as part of design characterization and after design or process changes.
Thereafter, parameters shall be guaranteed to the limits specified in Table II.
5
An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit
protection and is the condition of maximum power dissipation.
6
Load step transition time between 2.0
s and 10s.
7
Recovery time is measured from the initiation of the transient to where V
OUT has returned to within ±1.0% of VOUT at 50% load.
8
Input step transition time between 2.0
s and 10s.
9
Turn-on delay time measurement is for either a step application of power at the input or the removal of
ground signal from the inhibit pin (pin 2) while power is applied to the input.
