The TPS7A66-Q1 and TPS7A69-Q1 are low-dropout linear regulators designed for up to 40-V Vin operations. With only 12-µA quiescent current at no load, they are quite suitable for standby microprocessor control-unit systems, especially in automotive applications.

The devices feature integrated short-circuit and overcurrent protection. The devices implement reset delay on power up to indicate the output voltage is stable and in regulation. One can program the delay with an external capacitor. A low-voltage tracking feature allows for a smaller input capacitor and can possibly eliminate the need of using a boost converter during cold-crank conditions.

The devices operate in the –40°C to 125°C temperature range. The TPS7A6650EDGNRQ1 device is qualified to AEC-Q100 grade 0, operating in the –40°C to 150°C temperature range. These features suit the devices well for power supplies in various automotive applications.
