TS39100/1/2/3/4/5
1A Ultra Low Dropout Voltage Regulator
with Multi-Function
Application Information
The TS39100/1/2/3/4/5 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 VCE saturation voltage.
The TS39100/1/2/3/4/5 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 TS39100/1/2/3/4/5 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.
TS39100/1/2/3/4/5 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 TS39100/1/2/3/4/5 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 (TS39102/3/4) 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 VOUT is 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
TS39101/2/3/4/5 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 ViN
and pulled up to the maximum supply voltage.
Error Flag
TS39101/3 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 ViN or VOUT is required for proper operation. For
information regarding the minimum and maximum values of pull-up resistance, refer the graph as follow:
Thermal Resistance
Power SOP-8 Thermal Characteristic
TS39101/2/4 series’ performance is its power SOP-8 package featuring half the thermal resistance of a standard SOP8 package. Lower thermal resistance means more output current or higher input voltage for a standard SOP-8
package. Lower thermal resistance means more output current or higher input voltage for a given package size.
Lower thermal resistance is achieved by connect the four ground pins with the die attached pad to create a single
piece electrical and thermal conductor. This concept have been used by MOSFET production for years, proving very
reliable and cost effective for the user. As above thermal resistance figure. Thermal resistance consists of two main
elements, ΘJC (junction to case) and ΘCA (case to ambient). Using the power SOP-8 reduces ΘCA, the total thermal
resistance, ΘJA (junction to ambient) is the limiting factor in calculating the maximum power dissipation capability of the
o
device. Typically, the power SOP-8 have a ΘJC of 20 C/W dramatically , this is significantly lower than the standard
o
SOP-8 which is typically 75 C/W. ΘCA is reduced because pin 5~8 can be soldered directly to a ground plane which
significantly reduces the case to sink and sink to ambient thermal resistance.

Transient Response and 3.3V to 2.5V or 2.5V to 1.8V Conversion
TS39100/1/2/3/4/5 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 TS3910x 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.
Power Dissipation
From under curves, the minimum area of copper necessary for the par to operate safely can be determined. The
maximum allowable temperature rise must be calculated to determine operation along which curve.
Copper area lay out information
Determine the power dissipation requirements for the design along with the maximum ambient temperature at which
the device will be operated. Refer to power dissipation with copper area curve, which shows safe operating curves for
o
o
o
three different ambient temperatures with 25 C, 50 C, 85 C. From these curves, the minimum amount of copper can
be determined by knowing the maximum power dissipation required.
PD = (VIN- VOUT) * IOUT + VIN * IGND
If we used a 5.0V output device and a 6V input at an output current of 350mA, then the power dissipation is as follows:
PD = (6.0V- 5.0V) * 350mA + 5V * 4mA
PD = 350mW + 20mW
PD = 370mW
o
If the maximum ambient temperature is 85 C and the power dissipation is as above 375mW, the curve is shows that
2
the required area of copper is 80mm .
