2.瞬态电流限制器:瞬态电流限制器(Transient Current Limiter)是一种具有高电流限制能力的电子器件。它可以在电源启动时提供一个较低的电阻,以限制inrush电流的大小。当电源电压达到额定值后,瞬态电流限制器会恢复正常工作状态。 3.软启动电路:软启动电路是一种通过逐步增加电源电压来减少inrush电流的机制。它可以在电...
The inrush current limiting function prevents these conditions. After the LDO regulator turns on, it raises the output current slowly while limiting inrush current, thereby suppressing the output voltage overshoot and the input voltage drop. Therefore, inrush current limiting hel...
In addition, a large inrush current flows into the LDO regulator to charge the output smoothing capacitor connected to the VOUTpin. Inrush current occurs during the period from the time when the LDO regulator turns on to the time when the output voltage stabilizes. If...

A typical inrush current value, assuming that very low impedance is charging the capacitance, can be found from Equation 1: IINRUSH = CTOTAL ´ dV dT (1) where V is the final voltage to which the output of the LDO regulates. If we know the total capacitance, CTOTAL, at the LDO ...
To suppress the inrush current that occurs when the load switch IC is enabled, use a load switch IC with an inrush current limiting function, which suppresses the current flowing to the capacitor connected to the output terminal (VOUT) by slowing turning
