TK113xxB DEFINITION AND EXPLANATION OF TECHNICAL TERMS . OUTPUT VOLTAGE (VO) RIPPLE REJECTION RATIO The output voltage is specified with VIN = (VO(TYP) + 1 V) and IO = 30 mA. Ripple rejection is the ability of the regulator to attenuate the ripple content of the input voltage at the output. It is specified with 100 mVrms, 400 Hz superimposed on the input voltage, where VIN = VO+ 1.5 V. The output decoupling capacitor is set to 10 µF, the noise bypass capacitor is set to 0.1 µF, and the load current is set to 30 mA. Ripple rejection is the ratio of the ripple content of the output vs. the input and is expressed in dB. 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 load current and the junction temperature. OUTPUT CURRENT (IO MAX) The rated output current is specified under the condition where the output voltage drops 0.3 V below the value specified with IO = 30 mA. The input voltage is set to VO +1 V, and the current is pulsed to minimize temperature effect. STANDBY CURRENT Standby current is the current which flows into the regulator when the output is turned off by the control function (VCONT = VIN.) It is measured with V IN = 8 V (9 V for the 8 V output device.) SENSOR CIRCUIT Over current sensor CONTINUOUS OUTPUT CURRENT (IO) Normal operated output current. This is limited by package power dissipation. The overcurrent sensor protects the device in the event that the output is shorted to ground. Thermal sensor PULSE OUTPUT CURRENT (IO (PULSE)) Max pulsewidth 5ms, Duty cycle 12.5%: pulse load only LINE REGULATION (LINE REG) 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 = VO + 1V to V IN = VO + 6V. LOAD REGULATION (LOAD REG) 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 = VO +1 V. The load regulation is specified under two output current step conditions of 1 mA to 60 mA and 1 mA to 100 mA. QUIESCENT CURRENT (IQ) The thermal sensor protects the device in the event that 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 conditions. Reverse Voltage Protection Reverse voltage protection prevents damage due to the output voltage being higher than the input voltage. This fault condition can occur when the output capacitor remains charged and the input is reduced to zero, or when an external voltage higher than the input voltage is applied to the output side. The quiescent current is the current which flows through the ground terminal under no load conditions (IO = 0 mA) May, 1997 TOKO, Inc.

ON/OFF RESPONSE WITH CONTROL AND LOAD TRANSIENT RESPONSE The turn on time depends upon the value of the output capacitor and the noise bypass capacitor. The turn on time will increase with the value of either capacitor. The graph below shows the relationship between turn on time and load capacitance. If the value of these capacitors is reduced, the load and line regulation will suffer and the noise voltage will increase. If the value of these capacitors is increased, the turn on time will increase.

The obvious solution is to increase the size of the output capacitor. A more effective solution would be to add a capacitor to the noise bypass terminal. The value of this capacitor should be 0.1 µf or higher (higher values provide greater noise reduction). Although stable operation is possible without the noise bypass capacitor, this terminal has a high impedance and care should be taken to avoid a large circuit area on the printed circuit board when the capacitor is not used. Please note that several parameters are affected by the value of the capacitors and bench testing is recommended when deviating from standard values. May, 1997 TOKO, Inc. Page 9 TK113xx B DEFINITION AND EXPLANATION OF TECHNICAL TERMS (CONT.) INPUT-OUTPUT CAPACITORS Linear regulators require an output capacitor in order to maintain regulator loop stability. This capacitor should be selected to insure stable operation over the desired temperature and load range.

Page 10 May, 1997 TOKO, Inc. TK113xxB DEFINITION AND EXPLANATION OF TECHNICAL TERMS (CONT.) PACKAGE POWER DISSIPATION (PD) This is the power dissipation level at which the thermal sensor is activated. The IC contains an internal thermal sensor which monitors the junction temperature. When the junction temperature exceeds the monitor threshold of 150 °C, the IC is shutdown. The junction temperature rises as the difference between the input power (VIN X IIN) and the output power (VOUT X IOUT) increases. The rate of temperature rise is greatly affected by the mounting pad configuration on the PCB, the board material, and the ambient temperature. When the IC mounting has good thermal conductivity, the junction temperature will be low even if the power dissipation is great. When mounted on the recommended mounting pad, the power dissipation of the SOT-23L is increased to 600 mW. For operation at ambient temperatures over 25 °C, the power dissipation of the SOT-23L device should be derated at 4.8 mW/°C. The power dissipation of the SOT-89-5 package is 900 mW when mounted as recommended. Derate the power dissipation at 7.2 mW/°C for operation above 25 °C. To determine the power dissipation for shutdown when mounted, attach the device on the actual PCB and deliberately increase the output current (or raise the input voltage) until the thermal protection circuit is activated. Calculate the power dissipation of the device by subtracting the output power from the input power. These measurements should allow for the ambient temperature of the PCB. The value obtained from PD/(150 °C - TA) is the derating factor. The PCB mounting pad should provide maximum thermal conductivity in order to maintain low device temperatures. As a general rule, the lower the temperature, the better the reliability of the device. The Thermal resistance when mounted is expressed as follows: TJ = 0JA X PD + TA For Toko ICs, the internal limit for junction temperature is 150 °C. If the ambient temperature, TA is 25 °C, then: 150 °C = 0JA X PD + 25 °C 0JA X PD = 125 °C 0JA = 125 °C/ PD PD is the value when the thermal sensor is activated. A simple way to determine PD is to calculate VIN X IIN when the output side is shorted. Input current gradually falls as temperature rises. You should use the value when thermal equilibrium is reached. The range of currents usable can also be found from the graph below.

In design, take a vertical line from the maximum operating temperature (e.g. 75 °C) to the derating curve. 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 . May, 1997 TOKO, Inc.

For low temperature operation, select a capacitor with a low ESR at the lowest operating temperature to prevent oscillation, degradation of ripple rejection and increase in noise. The minimum recommended capacitance is 2.2 µF. Page 12 May, 1997 TOKO, Inc.
