VOLTAGE REGULATOR WITH ON/OFF SWITCH
FEATURES
■ High Voltage Precision at ± 2.4%
■ Active High On/Off Control
■ Very Low Noise
■ Very Small SOT-23L or SOT-89-5 Surface Mount
Packages
■ Internal Thermal Shutdown
■ Short Circuit Protection
DESCRIPTION
The TK112xxA is a low dropout linear regulator with a built­in electronic switch. The internal switch can be controlled by TTL or CMOS logic levels. The device is in the ON state when the control pin is pulled to a logic high level. An external capacitor can be connected to the noise bypass pin to lower the output noise level to 30 µVrms.
An internal PNP pass transistor is used to achieve a low dropout voltage of 70 mV (typ.) at 30 mA load current. The TK112xxA has a very low quiescent current of 180 µA at no load and 1 mA with a 30 mA load. The standby current is typically 100 nA. The internal thermal shutdown circuitry limits the junction temperature to below 150 °C. The load current is internally monitored and the device will shutdown in the presence of a short circuit or overcurrent condition at the output.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS
LINE REGULATION (LINE REG)
Line regulation is the relationship between change in output voltage due to a change in input voltage.
LOAD REGULATION (LOAD REG)
Load regulation is the relationship between change in output voltage due to a change in load current.
DROP OUT VOLTAGE (V
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 = V
+ 1 at a chosen load current. When the
OUT
output voltage has dropped 100 mV from the nominal, V
- V
is the dropout voltage. This voltage is affected by
OUT
load current and junction temperature.
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
DROP
)
IN
the SOT-23L is increased to 400 mW. For operation at ambient temperatures over 25 °C, the power dissipation of the SOT-23L device should be derated at 3.2 mW/°C. The power dissipation of the SOT-89-5 package is 800 mW when mounted as recommended. Derate the power dissi­pation at 6.4 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 + T
A
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/ P
D
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 shutdown. The junction temperature rises as the difference between the input power (VIN X IIN) and the output power (V
OUT
X I
) increases. The rate of
OUT
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
Page 30
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.

5.) In design, take a vertical line from the maximum operating temperature (e.g. 75 °C) to the derating curve.
6.) 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.

Copper pattern should be as large as possible. Power dissipation is 400 mW for SOT-23L and 800 mV for SOT­89-5. 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 µF.
INPUT/OUTPUT DECOUPLING CAPACITOR CONSIDER­ATIONS
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 resistance (ESR) over temperature. The type of capacitor is also important. For example, a 4.7 µF aluminum electrolytic may be re­quired for a certain application. If a tantalum capacitor is used, a lower value of 2.2 µF 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 -40 °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

DEFINITION AND EXPLANATION OF TECHNICAL TERMS (CONT.)
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. The recommended minimum capaci­tance for the TK112xxA is 2.2 µF. Please note that linear regulators with a low dropout voltage have high internal loop gains which requires 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.
NOISE BYPASS CAPACITOR SECTION
The noise bypass capacitor (CP) should be connected as close as possible to pin 3 and ground. The recommended value for CP is 0.01 µF. The noise bypass terminal has a high impedance and care should be taken if the noise bypass capacitor is not used. This terminal is susceptible to external noise and oscillation can occur when CP is not used and the solder pad for this pin is made too large.
