TK631xxH/S
CMOS LDO Regulator
1-. DESCRIPTION
4-. PIN CONFIGURATION
The TK631xxH/S is a CMOS LDO regulator. The
packages are the small and thin SON2017-6, and the
extremely versatile SOT23-5.
SON2017-6 (TK631xxH)
The IC is designed for portable applications with space
requirements, battery powered system and any electronic
equipment.
The IC does not require a noise-bypass capacitor.
The IC offers high accuracy (±1%) and low dropout
voltage.

* PD must be decreased at the rate of 2.9mW/C (FC-4) or 4mW/C (SON2017-6 , SOT23-5) for operation above 25C.
The maximum ratings are the absolute limitation values with the possibility of the IC breakage.
When the operation exceeds this standard quality can not be guaranteed.

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

12-. APPLICATIONS INFORMATION
12-1-. Stability
TK63115H/S
Linear regulators require input and output capacitors in
order to maintain the regulator's loop stability. If a 1.0µF
capacitor is connected to the output side, the IC provides
stable operation. However, it is recommended to use as
large a value capacitor as is practical. The output noise
and the ripple noise decrease as the value of the capacitor
increases.

A recommended value of the application is as follows.
CIn=1.0µF, COut=1.0µF
It is not possible to determine this indiscriminately.
Please confirm the stability in your design.

Fig.Error! Reference source not found. and Fig.12-2
show the stable operation area of output current and the
equivalent series resistance (ESR) with a ceramic
capacitor of 0.68µF. ESR of the output capacitor must be
in the stable operation area. Please select the best output
capacitor according to the voltage and current used. The
stability of the regulator improves as the value of the
output side capacitor increases (the stable operation area
extends.) Please use as large a value capacitor as is
practical.

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 500mW(SON2017-6/SOT23-5). Enduring
these losses becomes possible in a lot of applications
operating at 25C.

The overheating protection circuit operates when the
junction temperature reaches 150C (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.

Pd is easily calculated.
A simple way to determine Pd is to calculate VInIIn
when the output side is shorted. Input current gradually
falls as output voltage rises after working thermal
shutdown. You should use the value when thermal
equilibrium is reached.

2. Plot Pd against 25C.
3. Connect Pd to the point corresponding to the 150C
with a straight line.
4. In design, take a vertical line from the maximum
operating temperature (e.g., 75C) 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 (VIn,MAXVOut)=IOut (at 75C)
The above figure is multiple regulators being controlled
by a single On/Off control signal. There is concern of
overheating, because the power loss of the low voltage
side IC (TK63115H/S) 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.
The maximum output current at the highest operating
temperature will be IOut DPd (VIn,MAXVOut).
Please use the device at low temperature with better
radiation. The lower temperature provides better quality.
12-3-. On/Off Control
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.
Because the control current is small, it is possible to
control it directly by CMOS logic.

12-4-. Definition of term
Characteristics
Protections
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.
Maximum Output Current (IOut, MAX
)
Thermal Sensor
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.
The thermal sensor protects the device in case the
junction temperature exceeds the safe value (Tj=150C).
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 0 150V or more
HBM : 100pF 1.5k 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 5mA to 100mA.
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).
