TPS73618QDCQRQ1 Description

Short technical summary and product information.

The TPS73618QDCQRQ1 from Texas Instruments is a 400mA, high-accuracy, low-dropout (LDO) linear voltage regulator designed for automotive applications. It utilizes an NMOS topology for stability with low ESR output capacitors, and can even operate without an output capacitor.

 

Key electrical characteristics include a fixed 1.8V output voltage, an input voltage range of 1.7V to 5.5V, and an ultra-low dropout voltage of 75mV typical at 400mA. The device offers excellent load-transient response, low noise (30 µVRMS typical from 10 Hz to 100 kHz), and high PSRR.

 

Protection features include thermal shutdown and current limit protection. The regulator operates over an ambient temperature range of -40°C to +125°C. It is AEC-Q100 qualified, with specific ESD classifications for HBM and CDM.

 

This component is supplied in a SOT-223-6 surface-mount package. Its low quiescent current (under 1 µA in shutdown) makes it suitable for portable and noise-sensitive applications such as post-regulation for switching supplies and powering VCOs.
