  • TPS7B70-Q1  -  300-mA 40-V low-IQ LDO regulator with power good

Description

The TPS7A65-Q1 low-dropout linear voltage regulator is designed for low power consumption and quiescent current less than 25 µA in light-load applications. This device features integrated overcurrent protection and a design to achieve stable operation even with low-ESR ceramic output capacitors. 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, this device is well-suited in power supplies for various automotive applications.
