Input Capacitor
A 1
μ
F minimum capacitor is recommended to be
placed between V
IN
and GND.
Output Capacitor
It is required to prevent oscillation. 1.0
μ
F minimum
is recommended when C
BYP
is unused. 2.2
μ
F mini-
mum is recommended when C
BYP
is 100pF. The out-
put capacitor may be increased to improve transient
response.
Noise Bypass Capacitor
Bypass capacitor is connected to the internal voltage
reference. A 100pF capacitor connected from BYP to
GND make this reference quiet, resulting in a
significant reduction in output noise, but the ESR
stable area will be narrowed.
The start-up speed of the AP2210 is inversely
proportional to the value of reference bypass
capacitor. In some cases, if output noise is not a
major concern and rapid turn-on is necessary, omit
C
BYP
and leave BYP open.
Power Dissipation
Thermal shutdown may take place if exceeding the
maximum power dissipation in application. Under all
possible operating conditions, the junction tempera-
ture must be within the range specified under abso-
lute maximum ratings to avoid thermal shutdown.
To determine if the power dissipated in the regulator
reaches the maximum power dissipation (see figure
16, 17), using:

/W, no heatsink is
required since the package alone will dissipate
enough heat to satisfy these requirements unless the
calculated value for power dissipation exceeds the
limit.
Example (3.0V version):
I

is:

Therefore, for good performance, please make sure
that input voltage is less than 4.67V without heatsink
when T
