1)
If INPUT is connected to V
, 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 A6155.
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)
Thermal regulation is defined as the change in OUTPUT voltage at a time T after a change in power dissipation is applied,
excluding load or line regulation effects.
6)
The comparator and the voltage regulator have separate voltage references (see “ Block Diagram” Fig. 8).
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. 5).
