The APL5606/A is a low quiescent current and low dropout linear regulator which is designed with a P-channel pass MOSFET to power a DC fan and delivers output current up to 600mA. In adjustable mode, the output voltage follows the 1.6 times of the voltage on VSET pin to dynamically adjust the DC fan speed; in full speed mode, the internal P-channel MOSFET fully turns on to drive the DC fan with maximum supply voltage for full speed operation. The APL5606/A with low 140µA quiescent current is ideal for battery-powered system appliances. It is also stable with a low-ESR ceramic output capacitor (2.2µF typical) to reduce total cost and to minimize the PCB area required. The APL5606/A features current-limit (with foldback current) and over-temperature protections to protect the device against current over-loads and overtemperature. The APL5606/A is available in a SOP-8 package.
