The output voltage of APL5338A tracks the voltage at VREF
pin. An internal resistor divider is used to provide a half
voltage of VREF for VTTREF and VTT Voltage. The VTT
output voltage is only requiring 10µF of ceramic output
capacitance for stability and fast transient response. The
S3 and S5 pins provide the sleep state for VTT (S3 state)
and suspend state (S4/S5 state) for device when S5 and
S3 are both pulled low the device provides the soft-off for
VTT and VTTREF. The MSOP-10P, DFN2x2-8 and
TDFN3x3-10 packages with a copper pad is available
Packages

Input Capacitor
Layout Consideration
The APL5338A requires proper input capacitors to supply
surge current during stepping load transients to prevent
Figure 1 illustrates the layout. Below is a checklist for
your layout:

2. Output capacitors for VTT must be close to the pin with
the VIN limits the slew rate of the surge current, it is necessary to place the input capacitors near VIN as close as

3. VTTSNS should be connected to the output capacitors
possible. Input capacitors should be greater than 10µF. A
capacitor of 0.1µF (MLCC) or above is recommended for

between VTT and GND should be minimized.
4. VREF should be connected to VIN by a separate track.
Output Capacitor
VREF is the reference voltage of VTTREF, so avoid any
noise to get into the VREF.
The APL5338A needs a proper output capacitor to maintain circuit stability and improve transient response over
