*1:
The maximum output current is limited by power dissipation.
The maximum load current is the current where the output voltage decreases to 90% by increasing the output current at
T
j
=25°C, compared to the output voltage specified at V
In
=V
Out,TYP
+1V. The maximum load current indicates the current
at which over current protection turns on.
For all output voltage products, the maximum output current for normal operation without operating any protection is
200mA. Accordingly, LoaReg and V
Drop
are specified on the condition that I
Out
is less than 200mA.
General Note
Parameters with only typical values are just reference. (Not guaranteed)
The noise level is dependent on the output voltage, the capacitance and capacitor characteristics.
