General Description
The APL5605 is a low quiescent current and low dropout
linear regulator which is designed to power a DC fan
and delivers up to 600mA output current. The output
voltage follows the 1.6 times of VSET voltage and typi-
cal dropout voltage is only 220mV (typical) at 600mA
output current. The APL5605 with low 140µA quiescent
current is ideal for battery-powered system appliances
and stable with a 2.2µF ceramic output capacitor. The
features of current-limit (with foldback current) and over-
temperature protection protect the device against cur-
rent over-loads and over temperature. The APL5605 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-020C 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.
