General Description
APW7507C is a 1.5MHz high efficiency monolithic syn-
chronous buck regulator. Design with current mode
scheme, the APW7507C is stable with ceramic output
capacitor. Input voltage from 3V to 5.5V makes the
APW7507C ideally suited for single Li-Ion battery pow-
ered applications. 100% duty cycle provides low dropout
operation, extending battery life in portable electrical
devices. The internally fixed 1.5MHz operating frequency
allows the using of small surface mount inductors and
capacitors. The synchronous switches included inside
increase the efficiency and eliminate the need of an ex-
ternal Schottky diode.
The APW7507C is available in SOT-23-5/TSOT-23-5A
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 Greento 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).
