The APL5915 is a 1.5A ultra low dropout linear regulator.
This product is specifically designed to provide well sup-
ply volatage for motherboards NB and VGA card
applications. The IC needs two supply voltages, a control
voltage for the circuitry and a main supply voltage for
power conversion, to reduce power dissipation and pro-
vide extremely low dropout.
The APL5915 integrates many functions into a single
package. A Power-On-Reset (POR) circuit monitors both
supply voltages to prevent wrong operations. Thermal
shutdown and current limit functions protect the device
against thermal and current over-loads. POK indicates
the output status with time delay which is set internally. It
can control other converter for power sequence. The
APL5915 is enabled by other power system. Pulling and
holding the EN pin below 0.3V to shuts off the output.
The APL5915 is available in SOP-8P package which fea-
tures small size as SOP-8 and an Exposed Pad to reduce
the junction-to-case resistance, being applicable in 1~2W
applications.

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).
