Description

The OPTIREG™ linear voltage regulator TL T125D0EJ is a monolithic, integrated low-dropout voltage tracking regulator with high accuracy in a small PG-DSO-8 exposed pad package. The TL T125D0EJ is designed to supply off-board systems, for example sensors in powertrain management systems under the severe conditions of automotive applications. The TL T125D0EJ provides protection functions against reverse polarity as well as against short circuit to GND and to battery.

4 Block description and electrical characteristics

4.1 Functional description 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 TL T125D0EJ 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 must fulfill the requirements in the Functional range. 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:
• 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 160 is outside the maximum ratings and reduces the lifetime of the device. OPTIREG™ linear voltage regulator TL T125D0EJ High-precision voltage tracker

4.12 Functional description power good output

The power good output PG indicates an overvoltage or undervoltage condition of the tracker output. For this the device compares the output voltage VOUT to the reference voltage VADJ. The device indicates variations of the output voltage beyond the power good switching thresholds 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 release delay time tPG,r allows a microcontroller and an oscillator to start up. The power good release delay time is the time period from exceeding the power good switching thresholds until the device switches the power good output from "low" to "high" . The power good output PG is an open drain output that requires a pull-up resistor to a positive voltage rail. The pull-up voltage must maintain the absolute maximum ratings of power good PG, see Absolute maximum ratings.

5 Application information

Note: The following information is given as an example for the implementation of the device only and shall not be regarded as a description or warranty of a certain functionality, condition or quality of the device.

5.1 Application diagram

e.g. off board loads, sensors VREF PG I/OI/O CIN1CIN2 COUT RPG Figure 3 Application diagram Note: This figure is a simplified example of an application circuit. The function must be verified in the application.

5.2 Selection of external components

5.2.1 Input pin

Figure 3 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: 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. Aluminum electrolytic capacitor 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. OPTIREG™ linear voltage regulator TL T125D0EJ High-precision voltage tracker Target datasheet 24 Rev. 1.03 2022-11-10

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 Functional range. The typical performance graph Output capacitor ESRCOUT versusoutput current IOUT shows the stable operation 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 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 Adjust pin

Figure 3 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. Alternatively, the voltage reference can also be adjusted by a voltage divider.

5.2.4 Power good pin

The power good output is an open drain output, which requires a pull-up resistor to a positive voltage rail. The pull-up voltage must maintain the maximum ratings in Absolute maximum ratings. The example in Figure 3 uses the supply voltage VDD of a microcontroller as pull-up. To limit the external input current according to the requirement in Functional description power good output), the pull-up resistor must be sized depending on the pull-up voltage.

5.3 Thermal considerations

From the known input voltage, the output voltage and the load profile of the application, the total power dissipation can be calculated: PD = VIN − VOUT × IOUT + VIN × Iq 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: OPTIREG™ linear voltage regulator TL T125D0EJ High-precision voltage tracker

Target datasheet 25 Rev. 1.03 2022-11-10

RthJA, max = Tj, max − Ta PD Equation 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. Example Application conditions: VIN = 13.5 V VOUT = VADJ = 5 V IOUT = 100 mA Ta = 75°C Calculation of RthJA,max: PD = VIN − VOUT × IOUT + VIN × Iq = 13.5 V− 5 V × 100 mA+ 13.5 V× 3.5 mA= 0.897 W Equation 3 RthJA, max = Tj,max − Ta PD = 150°C − 75°C 0.897 W = 83.6 K/W Equation 4 As a result, the PCB design must ensure a thermal resistance RthJA lower than 83.6 K/W. According to Thermal resistance, at least 300 mm² heatsink area is required on the FR4 1s0p PCB, or the FR4 2s2p board can be used.
