         The TPS7A66-Q1 and TPS7A69-Q1 are low-dropout linear regulators designed for operating

circuits with input voltages up to 40V. With only 12μA quiescent current at no load, these devices

are ideal for standby microprocessor control unit systems, especially in automotive applications

where low power consumption is a key concern. The device features integrated short-circuit and

overcurrent protection.

         The device performs a reset delay at power-up to indicate that the output voltage is stable and


         The user can use an external capacitor to set this delay.

         The low-voltage tracking feature allows the use of smaller input capacitors and the possibility of eliminating the need to use a boost converter under cold crank conditions.

        The device operates over a temperature range of -40°C to 125°C.

        The TPS7A6650EDGNRQ1 device complies with the AEC-Q100 Class 0 standard and operates

over the –40°C to 150°C temperature range. These features are ideal for high efficiency, high

source density, and robustness requirements in power supplies in a variety of automotive
