Texas Instruments  TPS7A6033QKTTRQ1

The TPS7A60-Q1 and TPS7A61-Q1 comprise a family of low-dropout linear voltage regulatorsdesigned for low power consumption and quiescent current less than 25 µA in light-loadapplications. These devices feature integrated overcurrent protection and are designed to achievestable operation even with low-ESR ceramic capacitors. Power-on-reset delay is implemented duringdevice start-up to indicate that the output voltage is stable and in regulation. The power-on-resetdelay is fixed (250 µs typical), and can also be programmed by an external capacitor. A low-voltagetracking feature allows for a smaller input capacitor and can possibly eliminate the need of usinga boost converter during cold-crank conditions. Because of these features, these devices arewell-suited in power supplies for various automotive applications.
