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.
