(1µA maximum) and excellent power supply ripple
rejection (PSRR 75dB at 100Hz) in battery powered
applications, such as handsets, PDAs and in noise sensitive applications, such as RF electronics.

Note 2: Specifications in bold type are limited to -40oC≤TJ≤125oC. Limits over temperature are guaranteed by design, but not
tested in production.
Note 3: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
Note 4: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 0.1mA to 300mA. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 1% (TJ=25oC) or 2% (40oC≤TJ≤125oC) below its nominal value measured at 1V differential.
Note 6: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the
supply is the sum of the load current plus the ground pin current.

Note 2: Specifications in bold type are limited to -40oC≤TJ≤125oC. Limits over temperature are guaranteed by design, but not
tested in production.
Note 3: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
Note 4: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 0.1mA to 300mA. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 1% (TJ=25oC) or 2% (40oC≤TJ≤125oC) below its nominal value measured at 1V differential.
Note 6: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the
supply is the sum of the load current plus the ground pin current.

Figure 20. Typical Application of AP2210 (Note 7)
Note 7: Dropout voltage is 250mV when TA=25oC. In order to obtain a normal output voltage, VOUT+0.25V is the minimum
input voltage which will results a low PSRR, imposing a bad influence on system. Therefore, the recommended input voltage
is VOUT+1V to 13.2V. For AP2210-3.0 version, its input voltage can be set from 4V(VOUT+1V) to 13.2V.

Application Information
Input Capacitor
A 1µF minimum capacitor is recommended to be
placed between VIN and GND.
ture must be within the range specified under absolute 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:
TJ = PD*θJA + TA
PD=(VIN-VOUT)*IOUT+VIN*IGND
Output Capacitor
It is required to prevent oscillation. 1.0µF minimum
is recommended when CBYP is unused. 2.2µF minimum is recommended when CBYP is 100pF. The output capacitor may be increased to improve transient
response.
Where: TJ≤TJ(max), TJ(max) is absolute maximum ratings for the junction temperature; VIN*IGND can be
ignored due to its small value.
Noise Bypass Capacitor
Bypass capacitor is connected to the internal voltage
reference. A small 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. In order to keep the
output stability, it is recommended to use the bypass
capacitor no more than 100pF.
TJ(max) is 150oC, θJA is 200oC/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):
IOUT=300mA, TA=50oC, VIN(Max) is:
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
CBYP and leave BYP open.
(150oC-50oC)/(0.3A*200oC/W)+3.0V=4.67V
Therefore, for good performance, please make sure
that input voltage is less than 4.67V without heatsink
when TA=50oC.
Power Dissipation
Thermal shutdown may take place if exceeding the
maximum power dissipation in application. Under all
possible operating conditions, the junction tempera-
