3 Description
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°C to 125°C temperature range.
Because of these features, the TPS7B6925-Q1,
TPS7B6933-Q1, and TPS7B6950-Q1 devices are
well suited in power supplies for various automotive
applications.
