APL5607/A 600mA Linear Regulator for DC Fan Speed Control Features General Description • Low Dropout Voltage: 220mV (Typical) @ 600mA • Low Quiescent Current: 140µA • Enable/Shutdown Function • Output Voltage / VSET Voltage: 1.6 Times • Stable with Low ESR Ceramic Capacitors • Over-Temperature Protection • Current-Limit Protection with Foldback Current • Internal Soft-Start • SOP-8 and TDFN3x3-8 Packages • Lead Free and Green Devices Available (RoHS Compliant) Applications • Notebook Fan Driver • Motherboards • PC Peripherals • Battery-Powered System The APL5607/A is a low quiescent current and low dropout linear regulator which is designed to power a DC fan and deliver up to 600mA output current. The output voltage follows the 1.6 times of VSET voltage and typical dropout voltage is only 220mV (typical) at 600mA output current. The APL5607/A with low 140µA quiescent current is ideal for battery-powered system appliances and stable with a 2.2µF ceram […]
