TPS73719QDRBRQ1 Description

Short technical summary and product information.

The TPS73719QDRBRQ1 from Texas Instruments is an AEC-Q100 qualified, 1A ultra-low-dropout (LDO) linear voltage regulator designed for automotive applications. It features a fixed 1.9V output voltage and operates with an input voltage range of 2.2V to 5.5V.

 

This LDO regulator utilizes an NMOS pass transistor topology, offering excellent load transient response even with a small 1µF ceramic output capacitor. It boasts a typical dropout voltage of 130mV at 1A and a low quiescent current of less than 20nA in shutdown mode, making it suitable for portable and power-sensitive designs. Protection features include thermal shutdown and current limiting for enhanced reliability.

 

The TPS73719QDRBRQ1 is supplied in an 8-SON (3x3) package, suitable for surface mounting. Its operating temperature range is -40°C to +125°C (TA), ensuring performance in harsh environments. The regulator offers 1% initial accuracy and 3% overall accuracy over line, load, and temperature variations.
