2 Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output
voltages above 2.3 V.
3 Start-up time is defined as the time between the rising edge of EN to VOUT being at 90% of its nominal value.
4 Current-limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 3.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 3.0 V, or 2.7 V.

PCB LAYOUT CONSIDERATIONS
Heat dissipation from the package can be improved by increasing 06901-050
the amount of copper attached to the pins of the ADP121. However,
as can be seen from Table 6 and Table 7, a point of diminishing Figure 49. Example of WLCSP PCB Layout—Top Side
returns is eventually reached, beyond which an increase in the
copper size does not yield significant heat dissipation benefits.
Place the input capacitor as close as possible to the VIN and
GND pins. Place the output capacitor as close as possible to the
VOUT and GND pins. Use 0402 or 0603 size capacitors and
resistors to achieve the smallest possible footprint solution on
boards where area is limited.
