13. APPLICATIONS INFORMATION
13-1. Input / output capacitors
Linear regulators require input and output capacitors in order to maintain the regulator's loop stability. The equivalent
series resistance (ESR) of the output capacitor must be in the stable operation area. However, it is recommended to use
as large a value of capacitance as is practical. The output noise and the ripple noise decrease as the capacitance value
increases.
ESR values vary widely between ceramic and tantalum capacitors. However, tantalum capacitors are assumed to provide
more ESR damping resistance, which provides greater circuit stability. This implies that a higher level of circuit
stability can be obtained by using tantalum capacitors when compared to ceramic capacitors with similar values.
For output voltage device ³2.0V applications, the recommended value of CL³0.10mF.
For output voltage device ³1.5V applications, the recommended value of CL³0.22mF
The input capacitor is necessary when the battery is
discharged, the power supply impedance increases, or the
line distance to the power supply is long. This capacitor
might be necessary on each individual IC even if two or
more regulator ICs are used. It is not possible to
determine this indiscriminately. Please confirm the
stability while mounted.

CL=0.22 to

CNP=0.01mF
The IC provides stable operation with an output side
capacitor of
0.1mF (Vout³2.0V). If it is 0.1mF or more over the full
range of temperature, either a ceramic capacitor or
tantalum capacitor can be used without considering ESR.

13-2. Definition of term
¨ Over Current Sensor
The over current sensor protects the device when there is
excessive output current. It also protects the device if the
output is accidentally connected to ground.
¨ Output Voltage (Vout)
The output voltage is specified with Vin=(VoutTYP+1V)
and Iout=5mA.
¨ Thermal Sensor
¨ Maximum Output Current (Iout MAX)
The thermal sensor protects the device in case the
junction temperature exceeds the safe value (TJ=150°C).
This temperature rise can be caused by external heat,
excessive power dissipation caused by large input to
output voltage drops, or excessive output current. The
regulator will shut off when the temperature exceeds the
safe value. As the junction temperatures decrease, the
regulator will begin to operate again. Under sustained
fault conditions, the regulator output will oscillate as the
device turns off then resets. Damage may occur to the
device under extreme fault.
The rated output current is specified under the condition
where the output voltage drops 0.3V the value specified
with Iout=5mA. The input voltage is set to VoutTYP+1V
and the current is pulsed to minimize temperature effect.
¨ Dropout Voltage (Vdrop)
The dropout voltage is the difference between the input
voltage and the output voltage at which point the
regulator starts to fall out of regulation. Below this value,
the output voltage will fall as the input voltage is reduced.
It is dependent upon the load current and the junction
temperature.
Please reduce the loss of the regulator when this
protection operate, by reducing the input voltage or make
better heat efficiency.
¨ Line Regulation (LinReg)
Line regulation is the ability of the regulator to maintain a
constant output voltage as the input voltage changes. The
line regulation is specified as the input voltage is changed
from Vin=VoutTYP+1V to Vin=VoutTYP+6V. It is a pulse
measurement to minimize temperature effect.
*In the case that the power, Vin ´ Ishort(Short Circuit Current),
becomes more than twice of the maximum rating of its power
dissipation in a moment, there is a possibility that the IC is
destroyed before internal thermal protection works.
¨ Reverse Voltage Protection
¨ Load Regulation (LoaReg)
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
Load regulation is the ability of the regulator to maintain
a constant output voltage as the load current changes. It is
a pulsed measurement to minimize temperature effects
with the input voltage set to Vin=VoutTYP+1V. The load
regulation is specified output current step conditions of
5mA to 100mA.
¨ Ripple Rejection (R.R)
Vin
Vout
Ripple rejection is the ability of the regulator to attenuate
the ripple content of the input voltage at the output. It is
specified with 200mVrms, 1kHz super-imposed on the
input voltage, where Vin=Vout+1.5V. Ripple rejection is
the ratio of the ripple content of the output vs. input and is
expressed in dB.
GND
¨ ESD
MM: 200pF 0W 200V or more
HBM: 100pF 1.5kW 2000V or more
¨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).

How to determine the thermal resistance when
mounted on PCB
13-3. Board Layout
The thermal resistance when mounted is expressed as
follows:
Vin
Vout
Tj=qja´Pd+Ta
Tj of IC is set around 150°C. Pd is the value when the
thermal sensor is activated.
If the ambient temperature is 25°C, then:
150=qja´Pd+25
qja=125/Pd (°C /mW)
on/off
Np
The simple method to calculate Pd
PCB Material: Glass epoxy (t=0.8mm)
Mount the IC on the print circuit board. Short between
the output pin and ground. after that, raise input voltage
from 0V to evaluated voltage (see*1) gradually.
At shorted the output pin, the power dissipation PD can be
expressed as Pd=Vin ´ Iin.
Please do derating with 4.0mW/°C at Pd=500mW and
25°C or more. Thermal resistance (qja) is=250°C/W.
The input current decreases gradually as the temperature
of the chip becomes high. After a while, it reaches the
thermal equilibrium. Use this currrent value at the
thermal equilibrium. In almost all the cases, it shows
500mW or more.

The package loss is limited at the temperature that the
internal temperature sensor works (about 150°C).
Therefore, the package loss is assumed to be an internal
limitation. There is no heat radiation characteristic of the
package unit assumed because of the small size. The
device being mounted on the PCB carries heat away. This
value changes by the material and the copper pattern etc.
of the PCB. The losses are approximately 500mW.
Enduring these losses becomes possible in a lot of
applications operating at 25°C.

Procedure (When mounted on PCB.)
1. Find Pd (Vin´Iin when the output side is short-circuited).
2. Plot Pd against 25°C.
3. Connect Pd to the point corresponding to the 150°C with a
straight line.
The overheating protection circuit operates when there
are a lot of losses with the regulator (When outside
temperature is high or heat radiation is bad). The output
current cannot be pulled enough and the output voltage
will drop when the protection circuit operates. When the
junction temperature reaches 150°C, the IC is shut down.
However, operation begins at once when the IC stops
operation and the temperature of the chip decreases.
4. In design, take a vertical line from the maximum operating
temperature (e.g., 75°C) to the derating curve.
5. Read off the value of Pd against the point at which the vertical
line intersects the derating curve. This is taken as the maximum
power dissipation DPd.
6. DPd ¸ (Vinmax-Vout)=Iout (at 75°C)
The maximum output current at the highest operating
temperature will be Iout @ DPd ¸ (VinMax-Vout).
Please use the device at low temperature with better
radiation. The lower temperature provides better quality.

13-4. On/off control
13-5. Noise Bypass
It is recommended to turn the regulator off when the
circuit following the regulator is non-operating. A design
with little electric power loss can be implemented. We
recommend the use of the on/off control of the regulator
without using a high side switch to provide an output
from the regulator. A highly accurate output voltage with
low voltage drop is obtained.
The noise and the ripple rejection characteristics depend
on the capacitance on the Np terminal.
The ripple rejection characteristic of the low frequency
region improves by increasing the capacitance of Cnp.
A standard value is Cnp=0.001mF. Increase Cnp in a
design with important output noise and ripple rejection
requirements. The IC will not be damaged if the capacitor
value is increased.

The on/off switching speed changes depending on the Np
terminal capacitance. The switching speed slows when
the capacitance is large.

The above figure is 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 IC (TK11120CS) 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.
be observed.
