Texas Instruments  TPS7A6350QPWPRQ1

The TPS7A63-Q1 and TPS7A6401-Q1 are a family of low-dropout linear voltage regulatorsdesigned for low power consumption and quiescent current less than 35 µA in light-loadapplications. These devices, designed to achieve stable operation even with a low-ESR ceramicoutput capacitor, feature an integrated programmable window watchdog and overcurrent protection.Designers can program the output voltage using external resistors. A low-voltage tracking featureallows for a smaller input capacitor and can possibly eliminate the need of using a boost converterduring cold-crank conditions. The power-on-reset delay is fixed (250 µs typical), or an externalcapacitor can program the delay. Because of such features, these devices are well-suited in powersupplies for various automotive applications.
