Texas Instruments  TPS7A6601QDGNRQ1

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

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

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