The APL5606/A is a low quiescent current and low drop-
out 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 cur-
rent 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 over-
temperature. The APL5606/A is available in a SOP-8
package.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.
