DESCRIPTION
The TK116xxU series devices are low dropout, linear 3terminal regulators. An internal PNP pass-transistor is used in order to achieve low dropout voltage (typically 160 mV at 80 mA load current). The regulated output voltages of 3, 3.3, 5 and 9 V are available. The device has very low (400 A) quiescent current with no load and 2 mA with 60 mA load. An internal thermal shutdown circuit limits the junction temperature to below 150 C. The load current is internally monitored and the device will shut down in the presence of a short circuit at the output. The TK116xxU is available in the SOT-89 surface mount package.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS
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 = VOUT(TYP) + 1 V to VIN = VOUT(TYP) + 6 V. 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 = VOUT(TYP) +1 V. The load regulation is specified under three output current step conditions of 0 mA to 30 mA, 0 mA to 100 mA and 0 mA to 150 mA. DROPOUT VOLTAGE (VDROP) This is a measure of how well the regulator performs as the input voltage decreases. The smaller the number, the further the input voltage can decrease before regulation problems occur. Nominal output voltage is first measured when VIN = VOUT(TYP) + 1 V at a chosen load current. When the output voltage has dropped 100 mV from the nominal, VIN - VOUT is the dropout voltage. This voltage is affected by load current and junction temperature. GROUND CURRENT (IGND) Ground current is the current which flows through the ground pin(s). It is defined as IIN - IOUT, excluding control current. OUTPUT NOISE VOLTAGE This is the effective AC voltage that occurs on the output voltage under the condition where the input noise is low and with a given load, filter capacitor, and frequency range. THERMAL PROTECTION This is an internal feature which turns the regulator off when the junction temperature rises above 150 C. After the regulator turns off, the temperature drops and the regulator output turns back on. Under certain conditions, the output waveform may appear to be an oscillation as the output turns off and on and back again in succession. 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 shut down. 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 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 the radiation of heat is good, the device temperature will be low, even if the power loss is great. When mounted on the recommended mounting pad, the power dissipation of the SOT-89 package is 1000 mW. Derate the power dissipation at 8 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. The 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 = jA 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 = jA x PD + 25 C jA = 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 the December 1998 TOKO, Inc.

APPLICATION INFORMATION
INPUT/OUTPUT DECOUPLING CONSIDERATIONS CAPACITOR BOARD LAYOUT Copper pattern should be as large as possible. Power dissipation is 1000 mW for SOT-89. A low ESR capacitor is recommended. 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 F.
Voltage regulators require input and output decoupling capacitors. The required value of these capacitors vary with application. Capacitors made by different manufacturers can have different characteristics, particularly with regard to high frequencies and Equivalent Series Resistance (ESR) over temperature. The type of capacitor is also important. For example, a 4.7 F aluminum electrolytic may be required for a certain application. If a tantalum capacitor is used, a lower value of 2.2 F would be adequate. It is important to consider the temperature characteristics of the decoupling capacitors. While Toko regulators are designed to operate as low as -30 C, many capacitors will not operate properly at this temperature. The capacitance of aluminum electrolytic capacitors may decrease to 0 at low temperatures. This may cause oscillation on the output of the regulator since some capacitance is required to guarantee stability. Thus, it is important to consider the characteristics of the capacitor over temperature when selection decoupling capacitors. The ESR is another important parameter. The ESR will increase with temperature but low ESR capacitors are often larger and more costly. In general, tantalum capacitors offer lower ESR than aluminum electrolytic, but new low ESR aluminum electrolytic capacitors are now available from several manufacturers. Usually a bench test is sufficient to determine the minimum capacitance required for a particular application. After taking thermal characteristics and tolerance into account, the minimum capacitance value should be approximately two times this value. Please note that linear regulators with a low dropout voltage have high internal loop gains which require care in guarding against oscillation caused by insufficient decoupling capacitance. The use of high quality decoupling capacitors suited for your application will guarantee proper operation of the circuit.

APPLICATION NOTES
Maximize copper foil area connecting to all IC pins for optimum heat conduction. Place input and output bypass capacitors close to the GND pin. For best transient behavior and lowest output impedance, use as large a capacitor value as possible. The temperature coefficient of the capacitance and Equivalent Series Resistance (ESR) should be taken into account. These parameters can influence power supply noise and ripple rejection. In extreme cases, oscillation may occur. In order to maintain stability, the output bypass capacitor value should be minimum 1 F for tantalum electrolytic or 4.7 F for aluminum electrolytic at TA = 25 C.
