Texas Instruments  TPS7B6733QPWPRQ1

The TPS7B6701-Q1, TPS7B6733-Q1, and TPS7B6750-Q1 devices (TPS7B67xx-Q1) are low-dropoutlinear regulators designed for up to 40-V VIN operations. With only 15-µAquiescent current at light load that greatly increases the endurance time of the automotivebattery, the devices drive loads up to 450 mA.

The TPS7B67xx-Q1 family of devices features an integrated short-circuit and overcurrentprotection. Reset delay and power-good signal are implemented on power-up to indicate that theoutput voltage is stable and is in regulation. An external capacitor programs the delay. The enablefunction activates and deactivates the device with an I/O port from the MCU.

The device family operates at a temperature range of –40°C to 125°C.
