NCP4589DSQ18T1G ON Semiconductor

NCP4589 300 mA, Tri-Mode, LDO Linear Voltage Regulator The NCP4589 is a CMOS 300 mA LDO which switches to a low power mode under light current loads. The device automatically switches back to a fast response mode as the output load increases NCP4589 AE AE Vin Vout Vin Vout Vref Vref Current Limit Current Limit CE CE GND GND NCP4589Dxxxx NCP4589Hxxxx Figure 2.
