Automotive 750-mA, 26-V, low-dropout voltage regulator with enable

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 operation over the virtual junction temperature range –40°C to 125°C.
