General Description
The APL5501/2/3 are micropower, low noise, low drop-
out linear regulators. Operate from 2.7V to 6V input volt-
age and deliver up to 500mA. Typical output noise is just
50µV
RMS
with the addition of an external 0.1µF bypass ca-
pacitor in BP pin and typical dropout voltage is only 170mV
at 500mA loading. Designed for use in battery-powered
system, the low 50µA quiescent current makes it an ideal
choice.
Design with an internal P-channel MOSFET pass
transistor, the APL5501/2/3 maintain a low supply current,
independent of the load current and dropout voltage. Other
features include reverse current protection, thermal-shut-
down protection, and current-limit protection to ensure
specified output current and controlled short-circuit
current. The APL5501/2/3 regulators come in a miniature
SOT-23-5, SOT-89, SOT-89-5, SOT-223, SOP-8, TO-252-
3, and TO-252-5 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-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).
