open-in-new Find other Linear regulators (LDO)


The TPS7A6201-Q1 is a low-dropout linear voltage regulator designed for low power consumption and quiescent current less than 25 µA in light-load applications. This device features an integrated over-current protection, and is designed to achieve stable operation even with low-ESR ceramic output capacitors. The output voltage can be programmed using external resistors. The 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, this device is well suited in power supplies for various automotive applications.
