Note 1: Absolute Maximum Rating is limits beyond which damage to the device may occur. For guaranteed

specifications and test conditions see the Electrical Characteristics.

Note 2: The device is not guaranteed to operate outside its operating rating.

Note 3: Devices are ESD sensitive. Handling precautions recommended.

Note 4: The maximum allowable power dissipation is a function of the maximum junction temperature, T_J, the junction

to ambient thermal resistance, Ө_JA, and the ambient temperature, Ta. Exceeding the maximum allowable

power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The

effective value of Ө_JAcan be reduced by using a heat sink, Pd_(max)= (T_J(max)– Ta) / Ө_JA.

Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops -1% below its

nominal value measured at 1V differential.

Note 6: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the

ground pin current and output load current, I_GND= I_IN- I_OUTfor fix output voltage, , I_GND= I_IN- I_OUT+10mA for fix

reference output voltage in full load regulation.

1.5A Ultra Low Dropout Voltage Regulator

with Multi-Function

Application Information

The TS3915x series are high performance with low dropout voltage regulator suitable for moderate to high current and

voltage regulator application. Its 630mV dropout voltage at full load and over temperature makes it especially valuable

in battery power systems and as high efficiency noise filters in post regulator applications. Unlike normal NPN

transistor design, where the base to emitter voltage drop and collector to emitter saturation voltage limit the minimum

dropout voltage, dropout performance of the PNP output of these devices is limited only by low V_CEsaturation voltage.

The TS3915x series is fully protected from damage due to fault conditions. Linear current limiting is provided. Output

current during overload conditions is constant. Thermal shutdown the device when the die temperature exceeds the

maximum safe operating temperature. Transient protection allows device survival even when the input voltage spikes

above and below nominal. The output structure of these regulators allows voltages in excess of the desired output

voltage to be applied without reverse current flow.

Output Capacitor Requirement

The TS3915x series requires an output capacitor to maintain stability and improve transient response is necessary.

The value of this capacitor is dependent upon the output current, lower currents allow smaller capacitors. TS3915x

series output capacitor selection is dependent upon the ESR of the output capacitor to maintain stability. When the

output capacitor is 10uF or greater, the output capacitor should have an ESR less than 2Ω. This will improve transient

response as well as promote stability. Ultra low ESR capacitors (<100mΩ), such as ceramic chip capacitors, may

promote instability. These very low ESR levels may cause an oscillation and/or under damped transient response. A

low ESR solid tantalum capacitor works extremely well and provides good transient response and stability over

temperature aluminum electrolytes can also be used, as long as the ESR of the capacitor is <2Ω. The value of the

output capacitor can be increased without limit. Higher capacitance values help to improve transient response and

ripple rejection and reduce output noise.

Input Capacitor Requirement

An input capacitor of 1uF or greater is recommended when the device is more than 4” away from the bulk AC supply

capacitance or when the supply is a battery. Small, surface mount, ceramic chip capacitors can be used for bypassing.

Larger values will help to improve ripple rejection by bypassing the input to the regulator, further improving the integrity

of the output voltage.

Minimum Load Current

The TS3915x series is specified between finite loads. If the output current is too small leakage currents dominate and

the output voltage rises. A 10mA minimum load current is necessary for proper regulation.

Adjustable Regulator Design

The adjustable regulator versions (TS39152) is allow to programming the output voltage anywhere between 1.25 and

the 16V maximum operating rating of the family.

Two resistors are used. Resistors can be quite large up to 1MΩ, because of the very high input impedance and low

bias current of the sense comparator, the resistor values are calculated by:

Where V_OUTis the desired output voltage. Above application circuit shows component definition. Applications with

widely varying load currents may scale the resistors to draw the minimum load current required for proper operation.

Application Information (Continue)

Enable Input

TS39151/2/3 versions feature an active-high enable (EN) input that allows ON/OFF control of the regulator. Current

drain reduces to “zero” when the device is shutdown, with only micro-amperes of leakage current. The EN input has

TTL/CMOS compatible thresholds for simple interfacing with logic interfacing. EN may be directly tied to V_INand pulled

up to the maximum supply voltage.

Error Flag

TS39151 versions feature an Error Flag, which looks at the output voltage and signals an error condition when this

voltage drops 5% below its expected value. The error flag is an open-collector output that pulls low under fault

conditions. It may sink 10mA. Low output voltage signifies a number of possible problems, including an over-current

fault (the device is in current limit) or low input voltage. The flag output is inoperative during over temperature

shutdown conditions. A pull-up resistor from error flag to either V_INor V_OUTis required for proper operation. For

information regarding the minimum and maximum values of pull-up resistance, refer the graph as follow:

Transient Response and 3.3V to 2.5V or 2.5V to 1.8V Conversion

TS3915x has excellent transient response to variations in input voltage and load current. The device have been

designed to respond quickly to load current variations and input voltage variations. Large output capacitors are not

required to obtain this performance. A standard 10uF output capacitor, preferably tantalum, is all that is required.

Larger values help to improve performance even further. By virtue of its low dropout voltage, this device does not

saturate into dropout as readily as similar NPN base designs. When converting from 3.3V to 2.5V or 2.5V to 1.8V, the

NPN based regulators are already operating in dropout, with typical dropout requirements of 1.2V or greater,. To

convert down to 2.5V or 1.8V without operating in dropout, NPN based regulators require an input voltage of 3.7V at

the very least. The TS3915x regulator will provide excellent performance with an input as low as 3.0V or 2.5V

respectively. This gives the PNP based regulators a distinct advantage over older, NPN based linear regulators.

Output Sense

The fixed voltage regulator versions (TS39153) is connected to the output pin of the regulator. In critical applications,

small voltage drops are caused by the resistance (Rp) of PC traces between the regulator and the load. These may

be eliminated by connecting the sense pin to the output at the load as follow:

(Kelvin Sense Connection).

Thermal Characteristics

TS3915x series linear regulators are simple to use, the most complicated design parameters to consider are thermal

characteristics, thermal design requires the following application specification parameters:

 Maximum ambient temperature, T_A

 Output current, I_OUT

 Output voltage, V_OUT

 Input voltage, V_IN

Calculate the power dissipation of the regulator from these numbers and the device parameters from this datasheet,

where the ground current is taken from data sheet.

P_D= (V_IN– V_OUT) x I_OUT+ V_INx I_GND

The heat sink thermal resistance is determined by:

Ө_SA= (T_J(MAX)– T_A) / P_D– (Ө_JC+ Ө_CS)

Where T_J(MAX)≤ 125^oC and Ө_CSis between 0^oC and 2^oC/W. The heat sink may by significantly reduced in

applications where the minimum input voltage is know and is large compared with the dropout voltage and distribute

the heat between this resistor and the regulator. The low dropout properties of vertical PNP regulators allow

significant reductions in regulator power dissipation and the associated heat sink without compromising performance.

When this technique is employed, a capacitor of at least 1uF is needed directly between the input and regulator

ground.
