Description

The TPS7A60-Q1 and TPS7A61-Q1 comprise a family 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 integrated overcurrent 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. 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. Because of these features, these devices are well-suited in power supplies for various automotive applications.
