TPS7B4253QDDARQ1 Description

Short technical summary and product information.

The Texas Instruments TPS7B4253-Q1 is a 300mA, 40V adjustable voltage-tracking low-dropout (LDO) linear voltage regulator designed for automotive applications. It features AEC-Q100 qualification for temperature grade 1 (-40°C to +125°C).

 

This regulator boasts a wide input voltage range from -40V to 45V and an output voltage that adjusts from 1.5V to 40V. Key electrical characteristics include a very-low output tracking tolerance of ±4mV and a low dropout voltage of 320mV at 200mA output current. It also offers a low quiescent current of less than 4µA when disabled and typically 60µA at light loads.

 

Protection features include current-limit, thermal-shutdown, reverse polarity protection, and output short-circuit proof to ground and supply. The device is stable with a wide ESR range of 1mΩ to 20Ω and output capacitors from 10µF to 500µF.

 

Available in an 8-pin HSOIC PowerPAD package, it is suitable for automotive off-board sensors and low-current off-board modules where power supply protection is critical.
