CMOS LDO REGULATOR IC
TK630xxB
1. DESCRIPTION
4. PIN CONFIGURATION
The TK630xxB is a CMOS LDO regulator in very small
FC-4 package.
FC-4
The IC is designed for portable applications with space
requirements.
The IC does not require a noise-bypass capacitance.
The IC offers very low dropout voltage.
The output voltage is internally fixed from 1.5V to 4.2V
in 0.1V steps.

* PD must be decreased at rate of 2.9mW/°C for operation above 25°C.
The maximum ratings are the absolute limitation values with the possibility of damaging the IC.
When the operation exceeds this standard, quality can not be guaranteed.

8. ELECTRICAL CHARACTERISTICS
The parameters with min. or max. values will be guaranteed at Ta=Tj=25°C with test when manufacturing or
SQC(Statistical Quality Control) methods. The operation between -40 ~ 85°C is guaranteed by design.

*1: For VOut ≤ 2.0V, no regulations because VOP≤2.0V.
*2: The maximum output current is limited by power dissipation.
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.

The ripple rejection (R.R) characteristic depends on the characteristic and the capacitance value of the capacitor
connected to the output side. The R.R 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.

ceramic capacitor of 1.0µF. 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.
12. APPLICATIONS INFORMATION
12-1. Stability
Linear regulators require input and output capacitors in
order to maintain the regulator's loop stability.
An output capacitor of about 1µF is required between the
output pin and ground. 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.

The stability of the regulator improves if the value of the
input side capacitor is lager than the value of the output

An input and output capacitance of 1µF can be used when

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)
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 output voltage rises after working thermal
shutdown. You should use the value when thermal
equilibrium is reached. In many cases, heat radiation is
good, and Pd is 360mW or more.

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.
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 ÷ (VIn,MAX−VOut)=IOut (at 75°C)

(85°C)
150°C
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 360mW. 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
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.

12-3. On/Off Control
12-4. Influence by Light
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.
When this IC is exposed to strong light, the electrical
characteristics change. Please confirm the influence by
light in your design.
Because the control current is small, it is possible to
control it directly by CMOS logic.

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 (TK63015B) 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.

12-5. Definition of term
Characteristics
Protections
♦ Over Current Sensor
♦ Output Voltage (VOut
)
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.
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 0.9V times the value
specified with IOut=5mA. The input voltage is set to
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.
V
OutTYP+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 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
from VIn=VOut,TYP+1V to VIn=VOut,TYP+6V. It is a pulse
measurement to minimize temperature effect.
♦ ESD
MM : 200pF 0Ω 150V or more
HBM : 100pF 1.5kΩ 2000V or more
♦ 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 500mVrms, 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).
