TL750Mxx-Q1, TL751Mxx-Q1 www.ti.com SGLS312J – SEPTEMBER 2005 – REVISED JUNE 2011 AUTOMOTIVE LOW-DROPOUT VOLTAGE REGULATORS Check for Samples: TL750Mxx-Q1, TL751Mxx-Q1 FEATURES 1 Qualified for Automotive Applications 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, 8-V, and 12-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 o...
