Texas Instruments  TPS7A6533QKVURQ1

The TPS7A65-Q1 low-dropout linear voltage regulator is designed for low power consumptionand quiescent current less than 25 µA in light-load applications. This device features integratedovercurrent protection and a design to achieve stable operation even with low-ESR ceramic outputcapacitors. A low-voltage tracking feature allows for a smaller input capacitor and can possiblyeliminate the need of using a boost converter during cold crank conditions. Because of thesefeatures, this device is well-suited in power supplies for various automotive applications.
