Datasheet 7 Rev. 1.12 2021-05-28 OPTIREG™ linear voltage regulator TLS102B0MB High precision voltage tracker Block description and electrical characteristics 4 Block description and electrical characteristics 4.1 Functional description tracking regulator The regulator controls the output voltage VOUT by comparing it to the reference voltage applied to the EN/ADJ pin and driving a PNP pass transistor accordingly. The stability of the control loop depends on the following parameters: • output capacitor COUT • load current • IC temperature • poles and zeroes in the frequency response of the circuit including TLS102B0MB • external circuitry An input capascitor CIN is strongly recommended to buffer disturbances on the line. To ensure stable operation, the output capacitor’s capacitance and its equivalent series resistance ESR must fulfill the requirements in Table 3. The output capacitor must be sized suitably to buffer load transients. Connect each capacitor close to the pins. The internal protection features are designed to protect the device itself as well as the application from destruction in case of catastrophic events. These safeguards contain the following: • Output current limitation • Reverse polarity protection • Thermal shutdown Output current limitation In order to protect the pass element and the package from excessive power dissipation, the device limits the maximum output current at high input voltage. Reverse polarity protection The device allows a negative supply voltage. However, in reverse polarity condition several small currents flowing into the device increase the junction temperature. Thermal design must consider this effect,because in reverse polarity condition the overtemperature protection circuit does not operate. Thermal shutdown The overtemperature protection circuit is designed to prevent immediate destruction of the device 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. A junction temperature above 150°C is outside the maximum ratings and reduces the lifetime of the device.

The following external components at the input are recommended in case of possible external disturbance. Ceramic capacitor 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 as close as possible to the input pin of the voltage tracking regulator on the PCB.

Place CIN2 close to the input pin of the voltage tracking regulator on the PCB. Overvoltage suppression diode A suitably sized diode D1 suppresses high voltage beyond the maximum ratings of the circuit components and protects the device from damage due to overvoltage. 5.2.2 Output pin An output capacitor COUT is necessary for the stability of the voltage tracking regulator, see Table 3. The typical performance graph Output capacitor equivalent series resistance ESRCOUT versus output current IOUT shows the stable operating range of the device. In an automotive environment, ceramic capacitors with X5R or X7R dielectrics are recommended. Place COUT on the same side of the PCB as the device and as close as possible to both the OUT pin and the GND pin. In case of rapid transients of the input voltage or of the load current, COUT must be dimensioned properly to ensure the output stability in the application. 5.2.3 Enable/Adjust pin Figure 3 shows the typical input circuitry for a voltage tracking regulator. Typically the enable/adjust pin is connected to a fixed voltage reference reference that the regulator tracks. In the example of the application diagram EN/ADJs is connected to the supply voltage of a microcontroller. Alternatively, 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 by: PD = V IN − V OUT × I OUT + V IN × I q Equation 1 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 by: RthJA, max = T j, max − Ta PD Equation 2 with Datasheet 20 Rev. 1.12 2021-05-28 OPTIREG™ linear voltage regulator TLS102B0MB High precision voltage tracker Application information • 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 Table 4. Example Application conditions: • VIN = 13.5 V • VOUT = VADJ = 5 V • IOUT = 20 mA • Ta = 125°C Calculation of RthJA,max: PD = V IN − V OUT × I OUT + V IN × I q = 13.5 V − 5 V × 20 mA + 13.5 V × 0.9 mA = 0.182 W Equation 3 RthJA, max = Equation 4 T j,max − Ta PD = 150°C − 125°C 0.182 W = 137 K/W As a result, the PCB design must ensure a thermal resistance RthJA,max lower than 137 K/W. According to Table 4, at least 300 mm2 heatsink area is required on the FR4 1s0p PCB, or the FR4 2s2p board can be used.
