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).

Input Capacitor
Recommanded Minimum Footprit
The APL3534/A/B requires proper input capacitance to
supply current surge during stepping load transients to

prevent the input voltage rail from dropping. Because the
parasitic inductor from the voltage sources or other bulk
capacitors to the VIN pin limit the slew rate of the surge
currents, more parasitic inductance needs more input

capacitance.
A ceramic input capacitor (0.1 to 10µF) from VIN to GND,
located near the APL3534/A/B, is strongly recommended
to suppress the ringing during short circuit fault event.

Without the input capacitor, the output short may cause

Layout Consideration
The PCB layout should be carefully performed to maxi-

mize thermal dissipation and to minimize voltage drop,
droop and EMI. The following guidelines must be
considered:
0.05
1. Please place the input capacitors near the VIN pin as
close as possible.
2. Output decoupling capacitors for load must be placed
near the load as close as possible for decoupling highfrequency ripples.

Unit : Inch
SOT-23-5
3. Locate APL3534/A/B and output capacitors near the
load to reduce parasitic resistance and inductance for
excellent load transient performance.
4. The negative pins of the input and output capacitors
and the GND pin must be connected to the ground plane
of the load.
5. Keep VIN and VOUT traces as wide and short as possible.
