Description
TK111xxC is an integrated circuit of the silicon monolithic bipolar structure, and the regulator of
the low saturation output type with very little quiescent current(63μA).
The PNP power transistor is built into. The I/O voltage difference when the current of Typ.200mA is
supplied to the system is 0.2V. The voltage source can be effectively used
Therefore, It is the best for the battery use set.
The on/off function is built into IC. The current at standing-by mode becomes slight (pA level).
1.5-10.0V is arranged to the output voltage in 0.1V step. The output voltage is trimmed in high
accuracy. The best voltage for the set used will be able to be selected.
The over current sensor circuit and the reverse-bias over current obstruction circuit are built into.
It is a design not broken because an ESD is also high. It is possible to use (*O) at ease.
When mounting on PCB, the loss becomes about 500mW though the package is very small.
TK111xxC uses the circuit with very high stability in DC and AC.
The capacitor on the output side is steady in 0.1μF (1.8V≦Vout). The kind of this capacitor is not
asked. It is possible to use every type capacitor.
However, a good characteristic is shown the more overall larger this capacitor is.
The ripple rejection is 84dB at 400Hz and 80dB at 1kHz.

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 ≧2.0V applications, the recommended value of CL≧0.10μF.
For output voltage device ≧1.5V applications, the recommended value of CL≧0.22μF.
Vou
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=0.22μF
～0.1μF
Cin=0.22μF
～0.1μF
Cn=0.01μF
The IC provides stable operation with an output side capacitor of
0.1μF (Vout≧2.0V). If it is 0.1μF or more over the full range of temperature, either a
ceramic capacitor or tantalum capacitor can be used without considering ESR.

CL is not increased and it is more effective in the noise decrease to enlarge Cnp. The Cnp capacity
recommends 6800pF(682) or 0.01μF(103). The amount of the noise increases in a higher output voltage.
Please increase this capacity when low noise or more is demanded. IC does not operate abnormally about
0.1 and 0.22μF.

The ripple rejection characteristic depends on the characteristic and the capacity value of the capacitor
connected with the output side. The RR characteristic of 50KHz or more changes greatly in the capacitor on the

Please do derating with 4mW/℃ at Pd=500mW and 25℃ or more. Thermal resistance is (θja=250℃/W).
The heat loss of A and B is done in total. The package loss is limited at the temperature that the
temperature sensor of internal organs works (about 150℃). Therefore, the package loss is assumed to be
an internal limitation. There is no heat radiation characteristic of the package unit well because of the
small size. Heat runs away by the thing installed in PCB. This value changes by the material and the
copper pattern etc. of PCB. The loss's of about 500mW enduring becomes possible in a lot of applications
at 25℃ time.
The thermal resistance when mounted on PCB is requested.
Ta（Ｔa=25℃）
The operating chip junction temperature is shown by
150＝θja×pd＋25
θja×Ｐd＝125
Tj=θja×Pd+Ta.
Tj of IC is set to about 150℃.
Pd is a value when the overheating sensor is made to work.
θja＝（125／pd）(℃／mＷ)
Pd is easily obtained.
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.
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(SOT23-5) or more.
*1 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.
Pd is obtained by the normal temperature degree. The current that can be used at the highest operating
temperature is obtained from the graph of the figure below.
Procedure (When PCB is mounted, do).
1. Pd is obtained (Vin×Iin when the output side is short-circuited).

2. Pd is plotted on the line of 25℃.

3. Pd is connected with the point of 150℃ by the straight line.

Because the control current is a little, it is possible to control directly by CMOS logic.
The PULLDOWN resistance is built into the control terminal. (500KΩ)
The noise and the ripple rejection characteristic depend on the capacity of the terminal Vref and
change.
The ripple rejection characteristic of the low frequency region improves by the capacity of Cnp large.
A standard value is Cnp=0.0068μF. Please enlarge Cn in the design with an important output
noise and ripple rejection. IC does not break even if the capacitor is enlarged.
The switch speed of off/on changes depending on the capacity of the terminal Np. The switch speed
slows when capacity is large.

There is overheating worry because the power loss
of low voltage side (TK11120) IC is large.
Please decrease the electric power loss by using
resistance (R) as shown in a left chart if necessary.
When the overheating sensor works, the decrease of
the output voltage or the oscillation, etc. are
observed.

Definition of term
The measurement voltage (output voltage Typ+1V) has been described in the output voltage table.
・Output voltage (Vout) is measured by the following condition.
(Vin = output voltage Typ+1V) ：Output current (Iout=5mA).
・The maximum output current (Iout Max)ꢀIt is an input voltage (output voltage Typ+1V).
・It is an output current measured when the output voltage obtained this time decrease by
（VoutTyp.×0.9）by the thing to throw load current (Iout).
・The maximum output current will be measured in a short time so that the influence done by the
temperature of the chip is not done.
・The output current decreases when a low voltage operates.
Please refer to "Low input voltage-output current" graph for 2.1V or less.
・Drop out voltage (Vdrop) is an I/O voltage difference when the circuit stops the stability operation
decreasing in the input voltage. This voltage depends on load current (Iout) and junction
temperature (Tj).
・The input voltage is gradually decreased than the standard. It is a voltage difference between the
input and the output when the output voltage decreases by 100mV.
・Line regulation（Lin Reg）ꢀꢀThe input voltage is assumed to be a standard. It is an output
voltage change when this input voltage is made to change 5V higher. This measurement does
not influence by the temperature of IC and be measured in a short time.
・Load regulation（Load Reg）.. ꢀThe input voltage is assumed to be a standard. It is an output
voltage change to the change from 5 to 100mA and 200mA in the load current.
ΔVlo=｜VM1`－VM2`｜ꢀThis measurement does not influence by the temperature of IC and be
measured in a short time.
・Quiescent current（IQ）. Current which flows to terminal GND according to load current. It is
measured by(input current-output current)
・Ripple rejection（ＲＲ）..Input voltage is（Vout＋1.5V）and Iout=10mA CL=1.0μF CN=0.01μF
The Alternating Current of (f=1KHz 200ｍVRMS)is made to be superimposed to the power-
supply voltage. The ratio of the voltage and the input voltage that this shape of waves appears
to the output is measured. It obtains about 80dB in 1KHz. The ripple rejection improves when
the capacitor of the noise passing terminal in the circuit composition is large. However, the
response of on/off worsens.
・
Standing by current. Current which flows to IC when control is made 0 voltages. 8V input
voltage.
Protection circuit
・Short circuit sensor............ This operates when there are quite a lot of output currents (The
output was mistaken and connected to GND. The current flows to the set peak value.
・Overheating sensor. This operates when there are a lot of losses of the regulator (An outside
temperature is high and heat radiation is bad). When the temperature of the chip (Tj)reaches
about 150℃, IC does the operation stop. However, operation begins at once when the operation
stop is done and the temperature of the chip decreases. Therefore, it seems that on/off doing IC
oscillates at high speed when the output side is observed with the oscilloscope. Please improve
heat radiation or lower the input electric power. When heat radiation is bad, the forecast
package loss is not obtained.
* 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 bias current ........... An excessive current does not flow to
IC even if the input voltage becomes 0 with the voltage
impressed to the output side. (Input-GND short-circuit) Max
of the voltage of a reverse-bias is 6V.
