CMOS LDO Regulator

TK631xxB/H/S

! SON2017-6 (TK631xxH)

1. DESCRIPTION

The TK631xxB/H/S is a CMOS LDO regulator. The

packages are the very small 4-bump flip chip, the small

and thin SON2017-6, and the extremely versatile SOT23-

5.

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 accurracy (±1%) and low dropout

voltage.

The parameters with min. or max. values will be guaranteed at T_a=T_j=25°C with test when manufacturing or

SQC(Statistical Quality Control) methods. The operation between -40 ~ 85°C is guaranteed when design.

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.

12. APPLICATIONS INFORMATION

12-1. Stability

TK63115B

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.

C_In=1.0µF, C_Out=1.0µF

It is not possible to determine this indiscriminately.

Please confirm the stability in your design.

Fig12-3: Output Current vs Stable Operation Area

(TK631xxH/S)

Fig.12-2 and Fig.12-3 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.

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(FC-4), or 500mW(SON2017-

6/SOT23-5). 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

(Top View)

PCB Material : Glass epoxy

Size : 12mm×7mm×0.8mm

follows:

T_j=θ_ja×Pd+T_a

Please do derating with 2.9mW/°C at Pd=360mW(FC-4),

or with 4mW/°C at Pd=500mW(SON2017-6/SOT23-5),

and 25°C or more. Thermal resistance (θ_ja) is=250°C/W.

T_jof 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=θ_ja×Pd+25

θ_ja=125/Pd (°C /mW)

Fig12-11: The use of On/Off control

Pd is easily calculated.

A simple way to determine Pd is to calculate V_In×I_In

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.

Procedure (When mounted on PCB.)

1. Find Pd (V_In×I_Inwhen 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.

On/Off

Cont.

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 ÷ (V_In,MAX−V_Out)=I_Out(at 75°C)

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 (TK63115B/H/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 I_OutDPd ÷ (V_In,MAX−V_Out).

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.

12-4. Influence by Light(TK631xxB)

When TK631xxB (FC-4) 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.

12-5. Definition of term

Characteristics

Protections

♦ Over Current Sensor

♦ Output Voltage (V_Out

)

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 V_In=(V_OutTYP+1V)

and I_Out=5mA.

♦ Maximum Output Current (I_{Out, MAX}

)

♦ Thermal Sensor

The rated output current is specified under the condition

where the output voltage drops to 90% of the value

specified with I_Out=5mA. The input voltage is set to

The thermal sensor protects the device in case the

junction temperature exceeds the safe value (T_j=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 (V_Drop

)

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 V_In=V_Out,TYP+1V to V_In=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 V_In=V_Out,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 500mV_P-P, 1kHz super-imposed on the

input voltage, where V_In=V_Out,TYP+1.5V. Ripple rejection

is the ratio of the ripple content of the output vs. input and

is expressed in dB.

♦ Standby Current (I_Standby

)

Standby current is the current which flows into the

regulator when the output is turned off by the control

function (V_Cont=0V).
