11.8 Stability
The standard capacitor recommended for use on the output side is a ceramic capacitor equal to or greater than
1.0F. For operations at 2.4V or less, use at least a 2.2F capacitor.
Unstable Area
Stable Area
Figure 2. Stable operation area (COut≥0.47F)
Figure 2 indicates that operation is stable in the entire current range with a resistance of 1 or less (equivalent
series resistance or ‘ESR’) connected in series to the output capacitor. Generally, the ESR of a ceramic
capacitor is very low (several tens of m), and no problems should arise in actual use. If an application
requires use of a large ESR capacitor, connecting a ceramic capacitor with low ESR in parallel will enable
operations at this level. When parallel output capacitors are used, be sure to position the ceramic capacitor as
close to the IC as possible. The other capacitor connected in parallel may be located away from the IC. The IC
will not be damaged by the increased capacitance.
Input capacitors are necessary when the power supply impedance increases due to battery depletion or when
the line to the power supply is particularly long. There is no general rule that can be used to determine the
required number of capacitors used for such purposes. In some cases, only one capacitor is necessary for
several regulator ICs. In some cases, one capacitor is required for each IC. To determine the required number
of capacitors in a specific application, be sure to verify operation with all parts in the installed configuration.
Ceramic capacitors normally have specific temperature and voltage characteristics. Be sure to take the
operating voltage and temperature into consideration when selecting parts for use. We recommend parts
featuring B characteristics.

11.9 Operating Region and Power Dissipation
Power dissipation capability is limited by the junction temperature that triggers the built-in overheat
protection circuit. Therefore, power dissipation capability is regarded as an internal limitation. The package
itself does not offer high heat dissipation because of its small size. The package is, however, designed to
release heat effectively when mounted on the PCB. Therefore, the heat-dissipation value will vary depending
on the material, copper pattern, etc. of the PCB on which the package is mounted.
When the regulator loss is large (high ambient temperature, poor heat radiation), the overheat protection
circuit is activated. When this occurs, output current cannot be obtained, and an output voltage drop is
observed. When the junction temperature reaches the set value, the IC stops operating. However, after the IC
has stopped operation and the junction temperature lowers sufficiently, the IC restarts operation immediately.
The thermal resistance when mounted on PCB
The chip junction temperature during operation is expressed by

The junction temperature of the AP1154ADLxx is limited to approximately 145C by the overheat protection
circuit. PD is the value observed when the overheat protection circuit is activated. The following example is
based on an ambient temperature of 25C.

PD is 2400mW. If the temperature exceeds 25C, be sure to derate at -20mW/C.
Method of obtaining Pd easily
With the output terminal shorted-circuited to GND, gradually increase the input voltage and measure the input
current. Slowly increase the input voltage to about 10V. The initial input current value becomes the maximum
instantaneous output current value, but gradually lowers as the chip temperature rises, and ultimately reaches
a state of thermal equilibrium (through natural air cooling).
PD is calculated using the input value for input current and the input voltage value in the equilibrium state.
PD  VIn  I In
Procedure (conducted at the time of installation on PCB)
1: Obtain PD ( VIn  I In when output is short-circuited).
PD (mW)
2: Plot PD on the 25C line.
3: Draw a straight line between PD and the 145C line.
4: Extend a straight-line perpendicular from the point of the
designed maximum operating temperature (for example,
75C).
5: Extend a line to the left from the intersection of the derating
curve and the line drawn in 4, and read the PD value (this value
is DPD).

Try to achieve maximum heat dissipation in your design in order to minimize the part’s temperature during
operation. Generally, lower part temperatures result in higher reliability in operation.

11.10 Operating Region and Power Dissipation
It is recommended to turn the regulator off when the circuit following the regulator is not operating. A design
with small electric power loss can be implemented. Because the Vcont terminal current is small, it is possible
to control it directly by CMOS logic.

Figure 4. Parallel Connection Example
Figure 4 shows the multiple regulators being controlled by a single ON/OFF control signal. There is fear of
overheating, because the power loss of the low voltage side (AP1154ADL20) is large. The series resistor (R) is
put in the input line of the low output voltage regulator in order to prevent over-dissipation. The voltage
dropped across the resistor reduces the large input-to-output voltage across the regulator, reducing the power
dissipation in the device. When the thermal sensor works, a decrease of the output voltage, oscillation, etc.
may be observed.

12. Definition of term
Characteristics
 Output Voltage (Vout)
The output voltage is specified with Vin=Vout(typ)+1V and IOut=5mA.
 Output Current (IOut)
Output current, which can be used continuously (It is the range where overheating protection of the IC does
not operate).
 Maximum output current (IOut,Peak)
The rated output current is specified under the condition where the output voltage drops 0.9V times the value
specified with IOut=5mA by increasing the output current. The input voltage is set to Vout(typ)+1V and the
current is pulsed to minimize temperature effect.
 Dropout Voltage (VDrop)
It is the difference between the input voltage and the output voltage when the circuit stops stable operation by
decreasing the input voltage. It is measured when the output voltage drops 100mV from its nominal value by
decreasing the input voltage gradually.
 Line Regulation (LinReg)
It is the fluctuations of the output voltage value when the input voltage is changed.
 Load Regulation (LoaReg)
It is the fluctuations of the output voltage value when the input voltage is assumed to be Vout(typ)+1V, and
the output current is changed.
 Ripple Rejection (RR)
Ripple rejection is the ability of the regulator to attenuate the ripple content of the input voltage at the output.
It is measured with the condition of Vin= Vout(typ)+1.5V. Ripple rejection is the ratio of the ripple content
between the output vs. input and is expressed in dB
 Standby Current (IStandby)
Standby current is the current which flows into the regulator when the output is turned off by the control
function (VCont=0V).
Protections
 Over Current Protection
It is a function to protect the IC by limiting the output current when excessive current flows into the IC, such
as the output is connected to GND, etc.
 Thermal Protection
It protects the IC not to exceed the permissible power consumption of the package in case of a large power
loss inside the regulator. The output is turned off when the chip reaches around 145°C, but it turns on again
when the temperature of the chip decreases.
 Reverse Voltage Protection
Reverse voltage protection prevents damage due to the output voltage being higher than the input voltage.
This fault condition can occur when the output capacitor remains charged and the input is reduced to zero, or
when an external voltage higher than the input voltage is applied to the output side. Generally, a LDO
regulator has a diode in the input direction from an output. If an input falls from an output in an input-GND
short circuit etc. and this diode turns on, current will flow for an input terminal from an output terminal. In
the case of excessive current, IC may break.In order to prevent this, it is necessary to connect an Schottky
Diode etc. outside. This product is equipped with reverse bias over-current prevention, and excessive current
does not flow in to IC. Therefore, no need to connect diode outside.
