General Description

TS39300/1/2/3/4 are 3A ultra low dropout linear voltage regulators that provide low voltage, high current output with a

minimum of external components. The TS3930x series offers extremely low dropout (typically 400mV at 3A) and low

quiescent current (typically 36mA at 3A).

TS39300/1/2/3/4 is ideal for PC add-in cards that need to convert from standard 3.3V to 2.5V or 2.5V to 1.8V. A

guaranteed maximum dropout voltage of 500mV over all operating conditions allows the TS39300/1/2/3/4 to provide

2.5V from a supply as low as 3V, and 1.8V from a supply as low as 2.5V. The TS39300/1/2/3/4 also has fast transient

response for heavy switching applications. The device requires only 47uF of output capacitor to maintain stability and

achieve fast transient response.

On the TS39300/1/2/3/4, the enable pin may be tied to input voltage if it is not required for enable control.

3A Ultra Low Dropout Voltage Regulator

with Multi-Function

Application Information

The TS39300/1/2/3/4 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 TS39300/1/2/3/4 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 TS39300/1/2/3/4 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.

TS39300/1/2/3/4 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 TS39300/1/2/3/4 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 (TS39302) 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

TS39301/2/3/4 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

TS39301 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

TS39300/1/2/3/4 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 TS39300/1/2/3/4 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

Sense pin can be connected to the load and traces the load voltage, TS39303/4 will adjust the output voltage to

maintain the load at expected voltage.

Thermal Characteristics

TS39300/1/2/3/4 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.
