Inrush-Current Limit Function

R1190x Series has the function to limit the inrush-current, it limited approximately 0.3A when the voltage

regulator is turn ON. It is also possible to set time of the rush-current limitation by connecting capacitor with

The inrush-current is limited even if the capacitor is not connected with the DELAY pin. In this case, the time is

=0 by the formula above.

Though, if the value of time is insufficient for controlling the inrush-current, please connect the capacitor with

DELAY pin. The DELAY pin is used as OPEN when the capacitor is not used. Please use the DELAY pin as

OPEN when the capacitor is not used.

Auto-Discharge Function

R1190xxxxD series has the auto-discharge function. When "L" signal is put into the Chip-enable pin (CE), the

function.
