The TPS7A6650QDGNRQ1 is a 5V fixed output low-dropout (LDO) Linear Regulator designed for up to 40V Vin operations. With only 12µA 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.
