General Description
The APL5901/2 is a micropower, low noise, and low drop-
out linear regulator. Operate from 2.7V to 6V input voltage
and deliver up to 900mA. Typical output noise is just
50µV
RMS
with the addition of an external 0.1µF bypass ca-
pacitor in the BP pin and the typical dropout voltage is only
210mV at 900mA 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 APL5901/2 maintain a low supply current,
independent of the load current and dropout voltage. Other
features including reverse current protection, thermal-
shutdown protection, and current-limit protection ensure
specified output current and controlled short-circuit
current. The APL5901/2 regulator come in a miniature
SOT-89, SOT-89-5, SOT-223, SOP-8, TO-252, 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).
