3 Description
The TPS7B6701-Q1, TPS7B6733-Q1, and
TPS7B6750-Q1 devices (TPS7B67xx-Q1) are low-
dropout linear regulators designed for up to 40-V VIN
operations. With only 15-µA quiescent current at light
load that greatly increases the endurance time of the
automotive battery, the devices drive loads up to
450 mA.
The TPS7B67xx-Q1 family of devices features an
integrated short-circuit and overcurrent protection.
Reset delay and power-good signal are implemented
on power-up to indicate that the output voltage is
stable and is in regulation. An external capacitor
programs the delay. The enable function activates
and deactivates the device with an I/O port from the
MCU.
The device family operates at a temperature range of
–40°C to 125°C.
