DESCRIPTION
The TPS7A66xx and TPS7A69xx 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 micro 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. These features suit the devices well for power
supplies in various automotive applications.
