Description
The OPTIREG™ Linear TLS115D0 is a monolithic integrated low-dropout voltage tracking regulator with high
accuracy in small PG-DSO-8 exposed pad and PG-TSON-10 packages. The TLS115D0 is designed to supply offboard systems, for example sensors in powertrain management systems under the severe conditions of
automotive applications. Therefore, the TLS115D0 is equipped with protection functions against reverse
polarity and against short circuit to GND and battery.

High Precision Voltage Tracker
Block description and electrical characteristics

Block description and electrical characteristics
4.1
Tracking regulator
The regulator controls the output voltage VOUT by comparing it to the voltage applied to the ADJ pin and
driving a PNP pass transistor accordingly. The stability of the control loop depends on:
•
the output capacitor COUT
•
load current
•
chip temperature
•
the poles and zeroes in the frequency response of the circuit consisting of TLS115D0 and the load
An input capacitor CIN is strongly recommended for buffering the line influence.
To ensure stable operation, the output capacitor’s capacitance and its equivalent series resistance ESR
requirements given in the table “Functional range” on Page 8 must be maintained. For details see also the
typical performance graph “Output capacitor ESR(COUT) vs. output current IOUT” on Page 14. The output
capacitor must be sized suitably to buffer load transients.
Connect each capacitor close to the pins.
Protection circuitry prevents the TLS115D0 itself as well as the application from destruction in case of
catastrophic events. These safeguards contain:
•
output current limitation
•
reverse polarity protection
•
thermal shutdown
In order to protect the pass element and the package from excessive power dissipation the TLS115D0 reduces
the maximum output current at high input voltage.
The TLS115D0 allows a negative supply voltage. However, in reverse polarity condition several low currents
flowing into the TLS115D0 increase junction temperature. Thermal design must consider this effect, because
in reverse polarity condition the overtemperature protection circuit does not operate.
The overtemperature protection circuit prevents immediate destruction of the TLS115D0 in certain fault
conditions (for example a permanent short circuit at output) by switching off the power stage. After the chip
cools down, the regulator restarts. If the fault is not removed, then this leads to an oscillatory behavior of the
output voltage. Please note, that a junction temperature above 150°C is outside the maximum ratings and
reduces the lifetime of the TLS115D0.

Enable input
In order to minimize the quiescent current, the TLS115D0 can be switched to stand-by mode by setting the
corresponding enable input “EN” to “low”.
If the EN pin is not connected, then the “low” level from the internal pull-down resistor switches off the
regulator.

Block description and electrical characteristics

Power Good output
The Power Good output PG indicates an overvoltage or undervoltage condition of the tracker output. For this
the TLS115D0 compares the output voltage VOUT to the reference voltage VADJ. Variations of the output voltage
beyond the Power Good switching thresholds are indicated by a “low” signal at the Power Good output PG.
Transients shorter than the Power Good reaction time tPG,r do not trigger the Power Good output.
The Power Good output PG is an open collector output that requires a pull-up resisitor to a positive voltage
rail. The pull-up voltage must not exceed the absolute maximum ratings of Power Good PG (see “Absolute
maximum ratings” on Page 7).

Input pin

e.g. off board
loads, sensors
Figure 4 shows the typical input circuitry for a voltage tracking regulator. The following external components
at the input are recommended in case of possible external disturbance.
A ceramic capacitor CIN1 (100 nF to 470 nF) at the input filters high frequency disturbance imposed by the line,
such as ISO pulses 3a/b. Place CIN1 very close to the input pin of the voltage tracking regulator on the PCB.
An aluminum electrolytic capacitor CIN2 (10 µF to 470 µF) at the input smoothens high energy pulses, such as
ISO pulse 2a. Place CIN2 close to the input pin of the voltage tracking regulator on the PCB.
An accordingly sized overvoltage suppressor diode D1 suppresses high voltage beyond the maximum ratings
of the circuit components and protects the devices from damage due to overvoltage.

Application information
5.2.2
Output pin
An output capacitor COUT is mandatory for the stability of the voltage tracking regulator. The requirements for
COUT are described in the table “Functional range” on Page 8. The graph “Output capacitor ESR(COUT) vs.
output current IOUT” on Page 14 shows the stable operation range of the TLS115D0.
For automotive environment, ceramic capacitors with X5R or X7R dielectrics are recommended.
Place COUT on the same side of the PCB as the regulator itself and as close as possible to both the tracker
output pin and GND pin.
In case of rapid transients of input voltage or load current, COUT must be dimensioned properly to ensure the
output stability in the application.
5.2.3
Adjust pin
Figure 4 shows a typical Adjust circuitry for a voltage tracking regulator. Typically the Adjust Pin is connected
to a fixed voltage reference that the regulator tracks. In the example of the application diagram ADJ is
connected to the supply voltage of a microcontroller. The voltage reference can also be adjusted by a voltage
divider.
5.2.4
Power Good pin
The Power Good output is an open collector output, which requires a pull-up resistor to a positive voltage rail.
The pull-up voltage must not exceed the maximum ratings of the Power Good PG shown in “Absolute
maximum ratings” on Page 7. In Figure 4 the supply voltage VDD of a microcontroller is used as pull-up
voltage for example.
To limit the external input current according to the requirement (see “Power Good output” on Page 19), the
resistor must be sized depending on the pull-up voltage.
5.3
Thermal considerations
Knowing the input voltage, the output voltage and the load profile of the application, the total power
dissipation can be calculated:
(5.1)
P D = ( V IN – V OUT ) × I OUT + V IN × I q
with
•
PD: continuous power dissipation
•
VIN: input voltage
•
VOUT: output voltage
•
IOUT: output current
•
Iq: quiescent current
The maximum acceptable thermal resistance RthJA can then be calculated:
T j, max – T a
R thJA, max = ---------------------------PD
(5.2)
with
•
Tj,max: maximum allowed junction temperature
•
Ta: ambient temperature

OPTIREG™ Linear TLS115D0
High Precision Voltage Tracker
Application information
Based on the above calculation the proper PCB type and the necessary heat sink area can be determined with
reference to the specification in “Thermal resistance” on Page 8.
Example
Application conditions:
VIN = 13.5 V
VOUT = VADJ = 5 V
IOUT = 100 mA
Ta = 75°C
Calculation of RthJA,max:
PD = (VIN – VOUT) x IOUT + VIN x Iq
= (13.5V – 5V) x 100 mA + 13.5 V x 3.5 mA
= 0.897 W
RthJA,max = (Tj,max – Ta) / PD
= (150°C – 75°C) / 0.897 W
= 83.61 K/W
As a result, the PCB design must ensure a thermal resistance RthJA lower than 83.61 K/W. According to
“Thermal resistance” on Page 8, at least 300 mm2 heatsink area is required on the FR4 1s0p PCB, or the FR4
2s2p board can be used.
