TL750M-Q1, TL751M-Q1 Series www.ti.com SGLS312F – SEPTEMBER 2005 – REVISED JUNE 2007 AUTOMOTIVE LOW-DROPOUT VOLTAGE REGULATORS FEATURES • • • Qualified for Automotive Applications Customer-Specific Configuration Control Can Be Supported Along With Major-Change Approval Low Dropout Voltage, Less Than 0.6 V at 750 mA • • • • • • Low Quiescent Current TTL- and CMOS-Compatible Enable on TL751M Series Load-Dump Protection Overvoltage Protection Internal Thermal Overload Protection Internal Overcurrent-Limiting Circuitry DESCRIPTION The TL750M and TL751M series are low-dropout positive voltage regulators specifically designed for automotive applications. The TL750M and TL751M series incorporate onboard overvoltage and current-limiting protection circuitry to protect the devices and the regulated system. Both series are fully protected against load-dump and reverse-battery conditions. Load-dump protection is up to a maximum of 60 V at the input of the device. Low quiescent current, even during full-load conditions, makes the TL750M and TL751M series ideal for use in applications that are permanently connected to the vehicle battery. The TL750M and TL751M series offers 5-V and 8-V options. The TL751M series has the addition of an enable (ENABLE) input. The ENABLE input gives complete control over power up, allowing sequential power up or shutdown. When ENABLE is high, the regulator output is placed in the high-impedance state. The ENABLE input is TTL and CMOS compatible. The TL750Mxx and TL751Mxx are characterized for operation over the virtual junction temperature range –40°C to 125°C.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. Due to variation in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation. The package thermal impedance is calculated in accordance with JESD 51.

The output capacitor value and the parasitic equivalent series resistance (ESR) affect the bandwidth and stability of the control loop for these devices. For this reason, the capacitor and ESR must be carefully selected for a given operating temperature and load range. Figure 2 and Figure 3 can be used to establish the appropriate capacitance value and ESR for the best regulator transient response. Figure 2 shows the recommended range of ESR for a given load with a 10-µF capacitor on the output. Figure 2 also shows a maximum ESR limit of 2 Ω and a load-dependent minimum ESR limit. For applications with varying loads, the lightest load condition should be chosen because it is the worst case. Figure 3 shows the relationship of the reciprocal of ESR to the square root of the capacitance, with a minimum capacitance limit of 10 µF and a maximum ESR limit of 2 Ω. This figure establishes the amount that the minimum ESR limit shown in Figure 2 can be adjusted for different capacitor values. For example, where the minimum load needed is 200 mA, Figure 2 suggests an ESR range of 0.8 Ω to 2 Ω for 10 µF. Figure 3 shows that changing the capacitor from 10 µF to 400 µF can change the ESR minimum by greater than 3/0.5 (or 6). Therefore, the new minimum ESR value is 0.8/6 (or 0.13 Ω). This allows an ESR range of 0.13 Ω to 2 Ω, achieving an expanded ESR range by using a larger capacitor at the output. For better stability in low-current applications, a small resistance placed in series with the capacitor (see Table 1) is recommended, so that ESRs better approximate those shown in Figure 2 and Figure 3.
