Texas Instruments' TPS7B6701-Q1, TPS7B6733-Q1, and TPS7B6750-Q1 devices (TPS7B67xx-Q1) are low-dropout linear regulators designed for up to 40V VIN operations. With only 15µA quiescent current at light load that greatly increases the endurance time of the automotive battery, the devices drive loads up to 450mA. The TPS7B67xx-Q1 family of devices features an integrated short-circuit and overcurrent protection.
Reset delay and power-good signal are implemented on power-up to indicate that the output voltage is stable and is in regulation. An external capacitor programs the delay. The enable function 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.
