3 Description

The TPS7C84-Q1 is a wide input, low-dropout

regulator (LDO) supporting a 2.1V to 40V input

voltage range and up to 150mA of load current.

The TPS7C84-Q1 outputs either a fixed or adjustable

output. Fixed output options include 3.3V and 5V,

or set the output between 1.2V to 39V with the

adjustable device.

This device has a power-good (PG) output that

monitors the voltage at the feedback pin to indicate

the status of the output voltage. The EN input and

PG output are used for sequencing multiple power

supplies in the system.

The TPS7C84-Q1 is designed for up to 40V VIN

battery-connected applications. With a very wide

output voltage range, the device is designed for

for powering microcontrollers and controller area

networks and local interconnect network (CAN/LIN)

transceivers. The device is also designed for

providing bias supplies for gate drivers.
