Output
Rate in change of the output voltage that is caused when changing the ambient temperature while maintaining
the output current
Obtained from the following formula:
<Conditions>
Rate in change of the output voltage that is caused when changing the ambient temperature in the rated range
from -40°C to +85°C while setting the input voltage to V
CE pin = V
ISS1: No load, ISS2: I
<Conditions>
Current value at CE=V
Input current value that is obtained when changing the input voltage while setting CE pin = V
open (no connection) state.
<Conditions>
Current value at CE=V
Output current value required to run the overcurrent protection circuit.
Max. current value when the output voltage drastically lowers by the overcurrent protection circuit that
prevents overcurrent. (Max. IC output current)
<Conditions>
Set the input voltage to V
Value of the current that is supplied to the output when the output pin is short-circuited with V
current value required to run the short-circuit current protection circuit.
<Conditions>
Set the input voltage to V
Indicates the ratio with which AC components included in the input voltage appear in the output voltage, by
[dB].
<Conditions>
Input voltage = CE pin voltage = V
Frequency obtained by superposing the sine wave of 0.2[Vp-pAC] with the input voltage: 10[Hz] to
100[kHz]
Change of the output voltage that is caused when the input voltage is changed instantaneously.
<Conditions>
Change of the output voltage that is caused when the input voltage is changed from V
V
