Automotive high-voltage ultralow-IQ low-dropout regulator

The TPS7B69xx-Q1 device is a low-dropout linear regulator designed for up to 40-V VI operations. With only 15-µA (typical) quiescent current at light load, the device is suitable for standby microcontrol-unit systems especially in automotive applications. The devices feature an integrated short-circuit and overcurrent protection. The TPS7B69xx-Q1 device operates over a –40 to 125°C temperature range.
