The TLS115B0 is designed to supply offboard systems, for example sensors in powertrain management systems under the severe conditions of automotive applications. Therefore, the TLS115B0 is equipped with protection functions against reverse polarity and against short circuit to GND and battery. Up to a supply voltage of 45 V and output currents up to 150 mA, the output voltage follows the reference voltage that is applied to the ADJ input with very high accuracy. The required minimum reference voltage at ADJ is 2.0 V.

Data Sheet 9 Rev. 1.10 2020-03-19 OPTIREG™ Linear TLS115B0 High Precision Voltage Tracker Block description and electrical characteristics 4 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 TLS115B0 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 TLS115B0 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 TLS115B0 reduces the maximum output current at high input voltage. The TLS115B0 allows a negative supply voltage. However, in reverse polarity condition several low currents flowing into the TLS115B0 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 TLS115B0 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 TLS115B0.

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. Data Sheet 19 Rev. 1.10 2020-03-19 OPTIREG™ Linear TLS115B0 High Precision Voltage Tracker 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 TLS115B0. 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. 5.3 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 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 Data Sheet 20 Rev. 1.10 2020-03-19 OPTIREG™ Linear TLS115B0 High Precision Voltage Tracker Application information 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. 5.4 • Further application information For further information you may contact http://www.infineon.com/ Data Sheet 21 Rev. 1.10 2020-03-19 OPTIREG™ Linear TLS115B0 High Precision Voltage Tracker Package outlines 6 Package outlines 0.35 x 45˚ 1.27 0.41±0.09 2) 0.2 M 0.19 +0.06 0.08 C Seating Plane C A-B D 8x 0.64 ±0.25 D 0.2 6 ±0.2 8˚ MAX.
