The TPS7A60xx/TPS7A61xx is a series of low dropout linear voltage regulators designed for low power consumption and quiescent current less than 25 µA in light load applications. These devices feature an integrated over current protection and are designed to achieve stable operation even with low-ESR ceramic capacitors. Power-On Reset delay is implemented during device start up to indicate that the output voltage is stable and in regulation. The Power-On Reset delay is fixed (250 µs typical), and can also be programmed by an external capacitor. 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. Because of these features, these devices are well suited in power supplies for various automotive applications.
