If INPUT is connected to V
SS
, no reverse current will flow from the OUTPUT to the INPUT, however the supply current specified
will be sank by the OUTPUT to supply the A6250.
2)
The OUTPUT voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
3)
Regulation is measured at constant junction temperature using pulse testing with a low duty cycle. Changes in OUTPUT voltage
due to heating effects are covered in the specification for thermal regulation.
4)
The dropout voltage is defined as the INPUT to OUTPUT differential, measured with the input voltage equal to 5.0 V.
5)
Not tested.
6)
The comparator and the voltage regulator have separate voltage references (see Block Diagram Fig. 7).
7)
The comparator reference is the power-down reset threshold. The power-on reset threshold equals the comparator reference
voltage plus the comparator hysteresis (see Fig. 4).
