INPUT
The OUTPUT volt age tem per a ture co ef fi cient is defined as the worst case voltage change divided by the total temperature range.
Reg u la tion is mea sured at con stant junc tion tem per a ture using pulse testing with a low duty cycle. Changes in OUTPUT volt age
The com para tor and the volt age reg u la tor have sep a rate voltage references (see Block Di a gram Fig. 7).
If INPUT is con nected to V
will be sank by the OUTPUT to supply the A6250.
due to heating effects are covered in the specification for thermal regulation.
The com para tor ref er ence is the power-down re set thresh old. The power-on reset threshold equals the com para tor ref er ence
volt age plus the comparator hysteresis (see Fig. 4).
The drop out volt age is de fined as the INPUT to OUTPUT differential, measured with the input voltage equal to 5.0 V.
