The TPS7A66xx-Q1 and TPS7A69xx-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
The devices operate in the –40°C to 125°C temperature range. These features suit the
devices well for power supplies in various automotive applications.
