DESCRIPTION
The TPS7B6701-Q1, TPS7B6733-Q1, TPS7B6750-
Q1, TPS7B6750A-Q1 and TPS7B6750B-Q1 devices
are low-dropout linear regulators designed for up to
40-V V_IN operations. With only 15-uA quiescent
current at light load, 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.
