APPLICATIONS INFORMATION 12-1-. Stability TK63115H/S 100 Unstable Area 10 ESR ( ) Linear regulators require input and output capacitors in order to maintain the regulator's loop stability. If a 1.0F 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=1.0F, COut=1.0F It is not possible to determine this indiscriminately. Please confirm the stability in your design.

AP-MS0037-E-00 - 26 - 2011/02 [TK631xxB/H/S] 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. 12-2-. Layout Fig12-4: Layout example (TK631xxH) VCont VIn GND GND NC 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. VOut (Top View) PCB Material : Glass epoxy Size : 10mm7mmx0.8mm How to determine the thermal resistance when mounted on PCB The thermal resistance when mounted is expressed as follows: Tj=jaPd+Ta Tj of IC is set around 150C. Pd is the value when the thermal sensor is activated. If the ambient temperature is 25C, then: 150=jaPd+25 ja=125/Pd (C /mW) Fig12-5: Layout example (TK631xxS) VOut GND NC VIn GND VCont (Top View) PCB Material : Glass epoxy Size : 12mm7mmx0.8mm Please do derating with with 4mW/C at Pd=500mW(SON2017-6/SOT23-5), and 25C or more.

Therefore, the package loss is assumed to be an internal limitation. There is no heat radiation characteristic of the AP-MS0037-E-00 - 27 - 2011/02 [TK631xxB/H/S] Fig12-8: The use of On/Off control 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. Vsat REG On/Off Cont.

Find Pd (VInIIn when the output side is shortcircuited). 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 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 TK63142 4.2V TK63133 3.3V TK63115 1.5V On/Off Cont. 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. 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. AP-MS0037-E-00 - 28 - 2011/02 [TK631xxB/H/S] 12-4-. Definition of term Characteristics Protections Output Voltage (VOut) The output voltage is specified with VIn=(VOutTYP+1V) and IOut=5mA. 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. 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. 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=6V. It is a pulse measurement to minimize temperature effect. 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. Thermal Sensor 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. Please prevent the loss of the regulator when this protection operates, by reducing the input voltage or providing better heat efficiency. ESD MM : 200pF 0 150V or more HBM : 100pF 1.5k 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 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).
