With only 15-µA quiescent current at light load that greatly increases the endurance time of the automotive battery, the devices drive loads up to 450 mA. 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.
