*1: For VOut ≤ 1.8V , no regulations.
*2: The maximum output current is limited by power dissipation.
The maximum load current is the current where the output voltage decreases to 90% by increasing the output current at
Tj=25°C, compared to the output voltage specified at VIn=VOut,TYP+1V. The maximum load current indicates the current
at which over current protection turns on.
For all output voltage products, the maximum output current for normal operation without operating any protection is
200mA. Accordingly, LoaReg and VDrop are specified on the condition that IOut is less than 200mA.
General Note
Parameters with only typical values are just reference. (Not guaranteed)
The noise level is dependent on the output voltage, the capacitance and capacitor characteristic.

RR vs Frequency (VOut,TYP=1.2V (TK682xxAB1/M4))
The ripple rejection (RR) characteristic depends on the
characteristic and the capacitance value of the capacitor
connected to the output side. The RR characteristic of
50kHz or more varies greatly with the capacitor on the
output side and PCB pattern. If necessary, please confirm
stability of your design.

RR vs Frequency (VOut,TYP=1.2V (TK682xxAB1/M4))
General linear regulators require input capacitor and
output capacitor in order to maintain the regulator’s loop
stability.
The TK682xxAB1/M4 provides stable operation without

Refer to the following data that measured without input
and output capacitors.
The other electrical characteristics are equal to the
electrical characteristics when using input and output
capacitors.
Transient characteristics (influence of load deviation)
improve by using output capacitor (see the “Load
Transient” on page 29).
High frequency ripple can not be rejected without input
and output capacitors. Therefore, it is recommended that
external input and output capacitors be used when high
frequency ripple is expected.
Because a situation changes with each application, please
confirm to operation in your design.

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 its small size. Heat is
carried away from the device by being mounted on the
PCB. This value is directly effected by the material and
the copper pattern etc. of the PCB. The losses are
approximately 600mW. Enduring these losses becomes
possible in a lot of applications operating at 25°C.

The overheating protection circuit operates when the
junction temperature reaches 150°C (this happens when
the regulator is dissipating excessive power, outside
temperature is high, or heat radiation is bad). The output
current and the output voltage will drop when the
protection circuit operates. However, operation begins
again as soon as the output voltage drops and the
temperature of the chip decreases.

How to determine the thermal resistance when
mounted on PCB
The thermal resistance when mounted is expressed as
follows:
Tj=θja×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=θja×Pd+25
θja=125/Pd (°C /mW)
VOut1
VIn1
VIn2
VOut2
(Top View)
Pd is easily calculated.
A simple way to determine Pd is to calculate VIn×IIn when
the output side is shorted. Input current gradually falls as
temperature rises. You should use the value when thermal
equilibrium is reached. In many cases, heat radiation is
good, Pd is 600mW or more.
PCB Material : Glass epoxy
Size : 7mm×10mm×0.8mm
Please do derating with 4.8mW/°C at Pd=600mW and
25°C or more. Thermal resistance (θja) is=208°C/W.

12-3. On/Off Control
Fig.12-5: How to determine DPd
It is recommended to turn the regulator Off when the
circuit following the regulator is not 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.

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 ÷ (VIn,MAX−VOut)=IOut (at 75°C)
12-4. Influence by Light (TK682xxAB1)
When this IC is exposed to strong light, IC, the electric
characteristics change. Please confirm the influence by
light in your design.
The maximum output current at the highest operating
temperature will be IOut ≅ DPd ÷ (VIn,MAX−VOut).
Please use the device at low temperature with better
radiation. The lower temperature provides better quality.

12-5. Definition of term
Characteristics
Protections
♦ Output Voltage (VOut
The output voltage is specified with VIn=(VOutTYP+1V)
and IOut=5mA.
)
♦ 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.
♦ Maximum Output Current (IOut, MAX
)
The rated output current is specified under the condition
where the output voltage drops to 90% of the value
specified with IOut=5mA. The input voltage is set to
VOutTYP+1V and the current is pulsed to minimize
temperature effect.
♦ Thermal Sensor
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.
♦ 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 output voltage, the load current,
and the junction temperature.
Please prevent the loss of the regulator when this
protection operates, by reducing the input voltage or
providing 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
♦ ESD
MM : 200pF 0Ω 150V or more
HBM : 100pF 1.5kΩ 2000V or more
from VIn=VOut,TYP+1V to VIn=6V. It is
measurement to minimize temperature effect.
a pulse
♦ Load Regulation (LoaReg)
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=VOut,TYP+1V. The load
regulation is specified under an output current step
condition of 1mA to 50mA.
♦ 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
specified with 500mVP-P, 1kHz super-imposed on the
input voltage, where VIn=VOut,TYP+1.5V. Ripple rejection
is the ratio of the ripple content of 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).
