General Description
The APL5537 is a dual channel low dropout linear
regulator, which operates from 2.5V to 5.5V input voltage
and delivers up to 300mA output current at each channel.
Typical dropout voltage is only 240mV at 300mA.
The APL5537 with low quiescent current, high PSRR, and
low noise is ideal for battery powered system appliances.
Other features include logic-controlled shutdown mode,
over-temperature protection, short-circuit current-limit, and
current-limit protection to ensure specified output current.
The APL5537 is available in the TSOT-23-6A and TDFN
1.6x1.6-6 packages.

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.
